eT650D Temperature Gun by ennoLogic with NIST Certificate - Dual Laser Non-Contact Infrared Thermometer -58°F to 1202°F - Accurate Digital Surface IR Thermometer (Not for Body Temp)

This device, although similar to other cheaper IR thermometers, is far better. Quality control is a priority. According to ennologic.com, each unit is checked thoroughly for accuracy, before it is sold. They back that up each device with a 10 year warranty. The eT650D has features not found in most of the cheaper units and not even some of the more expensive ones. For example, you can log upto 20 measurements in memory, something more expensive IR thermometers won't do. You have the option to continually scan without having to keep pressing the trigger, again something the more expensive IR guns won't do. Dual lasers, again a more high end feature, useful for localizing the precise area to be temperature scanned, can be turned off. The display is bright when you want it, or you can turn it off. You have the ability to modify the emmisivity setting to improve the accuracy of your readings, just like with the more expensive F brand devices. You expect and have modes that give you Max, Min,Avg, and Difference between 2 readings. Having audible alarms that can be set for your chosen high or low temperatures is another nice feature. Moreover, the unit operates in a wider temperature than most: -50C to 650C (-58F to 1202F) I tested the accuracy of my device with both boiling water and a slurry of ice and water. The measurements were spot on. My only complaint with the device is the tight battery compartment, which makes fitting in the 9 volt battery into it a bit tricky. The wires must be looped and tucked in carefully along side the battery above the battery clips in order for the handle door to latch correctly. When I had trouble doing this, Customer Support came to my rescue by emailing me a picture showing me exactly how to do it. With a 22 hour battery life, I shouldn't have to be doing this often, although if I keep playing with this new device, I may be changing that battery pretty soon. .

I love this thermometer. If you want a certified thermometer, be sure to select the NIST calibrated one. It comes with a certificate that is good for a year. Don't complain that you did not get a certificate because you need to select that. It is a bit more expensive, however, if you want a serious big boy thermometer it is worth it. I'm saying that because I bought a toy one here and returned it. This is the real deal and worth every penny. I use it for everything from cooking, refrigeration, HVAC, computer cooling systems, and whatever you can think of that requires a thermometer. Also, don't complain about the lasers being misaligned. They are supposed to converge at a set distance and that's where you need to be to get the most accurate reading. If you need a solid, reliably accurate infrared thermometer this one is the one to get.

So this IRT is easy to use, accurate, and comfortable in the hand. Problem with being able to see the read out due to poor numbering size, but mostly shade. Could use a good back light to enhance the numbers. Too costly for that reason.

Good Quality equipment. It is amazing how many uses I have found for this item. Of course, it finds all the air leaks around doors and windows. I closed those gaps since I bought this item. Lately, I am seeing a snow storm in my drawer freezer in my Refrigerator. I use the gun to find the air leaks in the seal around the door. We started putting insulating foil in the attic. So far we got the west side done because that is the side that gets the afternoon heat. As the job progressed I was able to determine if the foil made a difference in keeping out the heat. Testing the finished and unfinished areas on that side with the gun I found a 20 to 30 degree difference. Who knew? Now I'm not reluctant to do the rest of the attic. I'm going to get one for my son for his birthday. He lives in the frozen north.

I decided on this temperature gun as it had a higher maximum temperature capability than most of the competition. There is even a higher max temp rated model available if needed. I was really looking for something with min max and avg capability and this does a great job with that. You can scan for a while then get he min max and avg for the entire scan period. It also can set an alarm for any low and high temp you want and then beep when the low or high is exceeded during scanning. There is nice backlighting which can be enabled or disabled . Warning this same capability can also disable the laser (not sure why i would) but you can. The box it came in was utterly high quality and kind of hard to open but certainly nice. The carrying case is decent and i might use it because it basically the exact size of he gun and no bigger. The gun feels nice and while not of the highest quality ... it’s not super cheap either imho. I’ll be careful with it. I did find the battery was difficult to put in without making the cover hard to close. Because I read this on another review I tried a number of configurations and got it to close pretty easily on the 6th try. Then i discovered the instructions included a one page thing saying to go Online and they would show a video on how to do this. If i has only read the instructions first! The instructions were pretty good and in lots of languages unfortunately. Because of the 10:1 ratio and the two lasers you have to be about 8” away for optional spacing of the two lasers. You can read further away but then the lasers are also pretty far away. I can aim at my TV and it got one laser on the top and the bottom of the screen. So it’s best to be fairly close to what you are measuring. All in all this seems like a great product. I bought it to measure my catalytic converters before and after to see if the cat is good or bad. (Generally temp is high and gets even higher after the cat if it’s working. On a broken cat the temp goes down. So could save you hundreds if you have just been told You need a new cat $1000-2000 . It might just be your sensors or something else.

I finally bought this expensive thermometer because I was tired of constantly purchasing cheap ones that either arrived broken or never worked to begin with. I have a reptile so I really need to be able to monitor the temperature in the different parts of his enclosure. I feel like I was buying new thermometers like every six months, so this will definitely save me money in the long run! I read about this model on somebody's survival blog, and it was highly recommended so I bought it. It came in a beautiful protective carrier and the first thing I noticed is that it was clearly WAY better-built that the cheap, crappy thermometers that I used to buy. The tutorials online are some of the best that I've seen on any topic, and between the videos and the simple written instructions, it did not take long at all for me to be familiar with all the functions. One thing I really like is that the dual lasers make it very easy to know exactly where to position the thermometer to get an accurate reading. The battery case is very easy to open, so I think they've updated it since previous reviewers mentioned it being hard. I'm so glad I finally bought a thermometer that works and will last! My only small disclaimer is that the lasers do say they technically emit a small amount of radiation that will harm you if you point it directly in your eyes so maybe don't use it to play with your cat. I did feel like all the cat logos were a bit deceiving for that reason. But overall, great product!!

Major dissatisfaction is with the stickiness of the black rubber grip - unable to clean, as attempting to clean with electronic wipes resulted in even stickier situation. Copious amounts of iso alcohol and elbow grease seemed to be most effective. Measurement of temperature is satisfactory - just very dissatisfied with the deterioration of the black rubber component.

Glad I purchased this item, it saves my wife allot of grief, Thank You
