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.

Any Klein tool is the best in class. It shows the temperature immediately and is extremely accurate. Obviously the best choice when buying a thermometer. Strongly recommended. It is also a good value. It is highly readable and very durable. The quality is very high. A great fit for any job.

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.

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

The response time is so slow that it's not really usable for me. The probe has a lot of thermal mass to be overcome if you're measuring near room temperature. Like under my armpit it took minutes and still didn't reach body temperature. An infrared thermometer works much better for my use cases. Other than the slow response time, I'm guessing it's a good thermometer. But I had to return it.

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.

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

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............

Does what it says on the tin.
