Very Handy and versatile!
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.

Works great
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.

Klein is the last word in everything they do.
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.

When in doubt, change the battery
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.

This is a keeper
Incredible. It does ambient temperature and contact temperature. It has a stainless steel probe and a removable protective case. If you’re looking for something sturdy, this is it.

Decent quality for the money, but no magnet and power button is finicky
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

Probably the best thermometer for checking supply and return air temperature. Would recommend

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