This requires no further explanation. On the positive side of the things, the fact that the display turns off so quickly does provide for better battery life. If this were the case there would be no way for you to adjust settings on the thermometer to accurately measure the temperature of the side of that aluminum pot (which has an emissivity value close to 0.1). Get the Etekcity 774 if youre unsure if you want to invest in a more expensive IR thermometer or you just want to take surface temperature readings for your own enjoyment. Youre in your kitchen performing a very simple but exciting science experiment to test the accuracy of your brand new IR thermometer youre boiling water inside an aluminum pot. What should you be looking out for to determine whether you can get away with buying a budget model or whether youll have no other option but to spend more on a more professional grade unit?

They take a long time to settle on the final measured reading at certain temperatures. Below freezing, around room temperature, and even up to 300 F it was quite accurate. It is guaranteed to be accurate no matter what. When comparing it side by side next to a professional grade thermometer like the Fluke 62 MAX+ its clear that the 630 was manufactured with low cost as a priority. The Etekcity 630 is not the second best IR thermometer we tested not even close. As you move away from the target the lasers move farther apart (as the spot gets larger).

if youre considering buying an extremely cheap unit these units are the only IR thermometers on the market that have a range limited to the point where you really need to pay attention to it before making a purchase. We recommend the Fluke 62 MAX+ as the best IR thermometer for most users. So think about whether this type of behavior will be acceptable to you. Single laser thermometers only show you the location of the spot youre measuring. Dual laser technology allows you to not only see the location of the spot youre measuring but also the exact size of the spot the two lasers show the edges of the spot. If you do youd be better off estimating the temperature of the surface yourself than trying to use the thermometer to do it.

A backlight to illuminate the thermometers LCD display in low light applications. During testing we knew the exact temperature of the surface we were measuring so this jumping back and forth between two temperatures wasnt a concern for us. Some units display this final temperature for over 20 seconds. Dual laser thermometers not only show you the location but also the size of the spot. You wont have the same luxury should you purchase only one budget IR thermometer for yourself. They do not read the final measured value nearly as fast. It normally retails for less than a quarter of the price of the Fluke 62 Max+. This isnt the case at room temperature but is often the case at extreme temperatures. Likewise, if its a good emitter this needs to be compensated for also. Fluke claims that this unit has been drop tested up to 9.8 ft. Budget units have hard plastic bodies that are sure to crack if you drop them on a hard surface from any height more than a few feet above the ground. Is it detected automatically? It allows for taking more precise measurements as a high D/S ratio equates to a very small measured spot size, It allows for the thermometer to be used in scenarios where you need to be far away from the surface that you want to measure. But, if youre willing to accept its quirks and youre willing to replace it if and when it breaks it provides a tremendous value thats difficult to walk away from. The average user wont have this luxury and might be confused by the two temperature readouts. The 774 does work. The 62 MAX+ gets accurate readings fast. Wires extend from the inside of the compartment to a bracket that fits over the top of the battery. If you need to measure the temperature of small spots at any distance youll need an IR thermometer with a high D/S ratio. The 774 comes with a 9V battery. And that 500 ms vs 300 ms isnt much of a difference either. Get the Fluke 62 MAX+ if you need an IR thermometer for professional work (HVAC, manufacturing, etc.) But then you run into a scenario like the one described earlier. Only concern yourself with an IR thermometers temperature range. Below 14 F the thermometers accuracy is only plus or minus 6 F. Accuracy between 14 F and 32 F is plus or minus 4 F. Accuracy above 32 F is plus or minus 2 F or 1% of the reading, whichever is greater. All of this sounds a bit complicated, doesnt it? Recall that a high D/S ratio is desirable because it provides two main benefits: As was true for the Fluke, we feel the 774s 12:1 D/S ratio is more than sufficient for the vast majority of applications. pool thermometer wireless digital thermometers infrared etekcity 1022 laser emissivity adjustable So how does it come to know the materials emissivity? But are things really this simple when it comes to IR thermometer accuracy? The second number represents the spot size. The 774 is small and compact one of the smallest IR thermometers we tested. Yes, you will have to identify the material youre scanning, look up its emissivity in a table, and input the correct emissivity value into the thermometer each time you take a reading (of a different material). But heres the thing. Always remember: an IR thermometer only measures the surface temperature of an object never its internal temperature. Get the Etekcity 630 if youre an average consumer looking for an IR thermometer to take temperature readings of a wide variety of different materials (the 630 features adjustable emissivity for this purpose) and you dont care about the thermometer being extremely accurate, durable, or reliable. Disabling it will result in some disabled or missing features. You may need to write down temperature data as you collect it. For Etekcity to be able to manufacture a budget IR thermometer with a higher D/S ratio than many professional grade units more than double, triple, even four or five times its price is actually quite the accomplishment. Interestingly, we found that not all thermometers activate as quickly as their manufacturer claims that they do. Note: an IR thermometer works great as a candy thermometer to temper chocolate, for example - or for measuring the temperature of lye when making soap. If you move both thermometers closer to the surface say 50 inches away the 50:1 model will have a spot size of 1 inch (still smaller) while the 10:1 model will have a spot size of 5 inches (still larger). The size of the spot changes depending on how far the thermometer is held away from the surface. But, if you measure the temperature of anything above a few hundred degrees F or well below freezing, it will show an initial reading at least 10 to 20 F above or below the actual temperature. And this is exactly the type of behavior you wont have a clue is a possibility when reading and comparing manufacturer specifications for accuracy and response time. The MAX+ has a quicker response time (300 ms for the MAX+ vs 500 ms for the MAX) But these are required steps for taking an accurate reading with an IR thermometer. One quirk we didnt like? The differences between these two units are the following: 1. Which is the correct temperature? If you plan on using it very infrequently, you really dont need to concern yourself with its size or ergonomics. If you do absolutely need an IR thermometer with a high D/S ratio our recommendation would be the Fluke 572. The reading will then slowly move up or down until it settles on a final temperature. Battery replacement is a little more complicated than you might expect a screwdriver is required to access the battery compartment. The 774 has a manufacturer specified response time of 800 ms but suffers from the same delayed activation and temperature readout as the 630. if youre buying one for professional use and you need to measure the temperature of materials that exceed certain known extreme temperatures. This means that the 774 will only give accurate readings for materials with an emissivity value at or close to 0.95. Its a really good thermometer one of the best IR thermometers on the market. But if you need to determine whether you have a fever or not youll need to measure your bodys internal temperature and for that youll need an oral or rectal thermometer. It reads out temperature almost immediately upon pulling its trigger. Needless to say, when we used the 774 to measure more reflective objects with lower emissivity values (polished aluminum, for example), its readings were highly inaccurate often 10, 20 up to 100 degrees above or below the actual temperature. The more lasers, the better. And its limited temperature range (more on that further down below) makes it inoperable at extremely high temperatures (above 716 F). Its backlight will turn on and warning symbols and the like will display immediately. At this point 2 seconds later it shows an initial reading. Heres the problem. And we absolutely do not recommend it for professional use. An IR thermometer can be used for more than just measuring one temperature at one pinpoint location. Only when you release the trigger is a final temperature displayed on the screen. If you need to measure a relatively small spot from a large distance away from the surface then youll need an IR thermometer with a high D/S ratio. The 62 MAX+ provides all of the extra features you would come to expect from a unit in its price range. Heres the problem. Such a thermometer is guaranteed to be extremely inaccurate taking readings of any material that doesnt have an emissivity value of 0.95 the fixed value that most fixed emissivity thermometers are set to. If you want an IR thermometer that can give you accurate readings no matter what material youre measuring, a unit with adjustable emissivity (like the Etekcity 630) is really the only way to go. Yes, you certainly could estimate the distance between you and the target and then use the thermometers D/S ratio to estimate the size of the spot being measured. When doing so, the 62 MAX+ can show you the average, minimum, and maximum temperature measured during the entire time you were holding down the trigger. The Fluke 62 MAX+ has a temperature range of -22 F to 1202 F. This range is more than sufficient for the majority of applications. infrared thermometer etekcity 1022d Only look to purchase a thermometer with a higher D/S value if you know that youll need it for a very specific application and youre prepared to spend a good amount of money for it. Yes, there are less expensive thermometers out there. The Etekcity 774 does not feature adjustable emissivity. You can always move closer to the surface with a low D/S ratio thermometer to obtain a small spot size (this negates advantage #1 above). Just remember to adjust its emissivity setting when necessary. Its high quality display is easy to read, backlit if you want it to be, and is large enough to provide supplemental data like the current emissivity setting and the maximum, minimum, or average temperature of the scanned surface without issue. For example, the Etekcity 630 requires you to hold down a button for 3 seconds to switch between degrees Celsius and degrees Fahrenheit. It has very few of the features of more expensive units. A low and high temperature alarm. The answer price. Everythings made up of atoms. During testing, we found it to be quite accurate reading the temperature of common household items like paper, paint, and food near room temperature. During testing, we found it was very easy for these wires to get pinched by the part of the handle that swings back and forth to open and close the battery compartment. You can place non-reflective tape (with an emissivity value of 0.95) over the surface you need to measure and then take a reading of the area covered by the tape. That is because even units with a more limited range still have a very wide range of several hundred degrees Fahrenheit. The MAX+ has a wider temperature range (up to 1202 F for the MAX+ vs up to 932 F for the MAX) The Etekcity 630 can measure surface temperatures between -58 F and 1076 F. This range should be adequate for the majority of applications. The movement of these atoms gives off IR radiation. The Fluke 62 MAX+ has one of the larger LCD displays of any of the IR thermometers we tested. infrared thermometer etekcity 1022d
