Customers say
Customers find the thermometer sturdy and reliable, with highly accurate readings and consider it a must-have for HVAC work. The display and control buttons are very small, and while some find it easy to use, others note it’s not an instant read as advertised. Moreover, the battery life receives mixed feedback, with customers reporting that the batteries come dead, and functionality is also mixed, with some saying it works well while others find it non-functional.

Small display but works great
Display is small, but if your a hvac tech that always loses these temp probes, this is cheap to replace and it works great.

Accurate, small, easy to use
We have several thermometers around the house and they all provide different readings, so we wanted one accurate thermometer to verify the true reading. It works great.

Great for home owners NOT so for professionals.
Kline Quality and price.It’s for a home owner not a tech as I oncewas. Lots of nice features but it’s way to slow in display readings for a professional were time is money.Also no magnet to hold it in place checking HVAC temps. Batteries are expensive to replace LR44.Why did you pick this product vs others?:Price and quick shipping.

Klein Makes Great Products
Was not expensive but proforms like a high quality lab grade thermometer, the protective plastic cover works well to insert in a window air conditioner vent. Used to determine if an air conditioner was cooling, made my laser thermometer redundant. I have purchased many Klein tools lately as they work well and are trusted products for people in the trade.

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 Iâm a bit more careful clipping it, but itâs been fine and Iâve had it in my pocket permanently during the 2 weeks. Itâs 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 Iâd bought it sooner…………
