Klein Tools ET05 Digital Pocket Thermometer, HVAC Instant Read Thermometer with Backlit Display, Wide Measurement Range, Fahrenheit and Celsius

The thermometer works exactly as it says it should. It is super responsive, the battery lasts forever on it and for how small it is. It is absolutely perfect for my home inspections. Never had an issue with accuracy, just all around solid product.

Excellent thermometer at a very good affordable price.Good company who makes it as well.

I got this for a HVAC tool, but it also puts my meat thermometer to shame! It also checks room temps. Love the light. Very fair price and super fast and easy to use.

almost gave this thermometer a bad review because it arrived with a low battery, but once I replaced it, it worked perfectly. I just clip it onto the AC vent and turn it on whenever I need to check the temperature. It’s fairly accurate when compared to my other thermometers—maybe a degree or two off, but still good enough. Another plus is how quickly it reads the temperature, which is definitely an advantage.

Needed to measure the temperature of the intake and exhaust ports of my hybrid water heater to check if the compressor was functioning properly. Worked quickly to show temperatures and that the compressor wasn't working.

No complaints whatsoever, it's a digital thermometer with hold, average, min and max functions and a backlight. The protective cover can be used to extend the length of the thermometer. It does take a while to settle and get a final reading but I feel that's to be expected and would occur with any digital thermometer. I use it for checking supply air on HVAC.

This is a good thermometer for the price. Doesn’t really feel cheap, has survived multiple drops from ceiling height. It does not have a magnet, so if you are using it to measure temperature in ducts you have to hold it. The power button on mine is finicky. It works, but sometimes you have to press multiple times to get it to turn on. Overall I’d recommend it, it’s good for the money but I really wish it had a magnet

Takes accurate temps and I like the high and low reading. Unfortunately to easy to leave in duct work.

Because this device digit not show properly

Pero preciso y se le ve que puede ir al bolsillo o caja con otras herramientas que no muere de contacto

After loosing a few UEI folding type thermometers I found theses. Yes the folding type is definitely better but they have jumped in cost by a lot. These don't have magnets in them, the higher end ones do but if you plan your use of them you do not need them. Cheap tool to add to the bag.

Excelente termómetro para lecturas de salida de aire en autos y minisplits por ejemplo

Been using this for a short period ( 2 weeks I think ) and so far its impressed me. I swapped it out for my works calibrated Regin unit which costs £240, that seems to be plagued with issues regarding with water ingress around where the probes are plugged in. The Klein so far has out performed the Regin despite the cost difference. There seems to be many complaints about the belt/pocket clip, mine has been in/out of my pocket dozens of times without issue. Maybe I’m a bit more careful clipping it, but it’s been fine and I’ve had it in my pocket permanently during the 2 weeks. It’s a fraction of the size/weight of my other unit, now I carry this and a Klein 11 in 1 screwdriver which has transformed my 6 monthly temperature testing of TMV valves. I first spotted it approx 2 years ago, I wish I’d bought it sooner............
