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

Good thermometer for hvac works as described

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.

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.

Decent thermometer, needs a magnet and bigger screen. My UEI is better.

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.

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

Handy tool, but limited by its size. Using for automotive HVAC and sadly the tool is too thick to clip to the vent fins of most cars. It does read accurately, quickly and retains a readout long enough to read, or has the option to display the highest temperature over the time the tool is on. I still use it daily, but it holds me up trying to clip it onto something in the vent before my test drive.

When working in the trades we need reliable tools. These are just that. Now if I could stop forgetting them on jobsites that would be nice.

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