Very Handy and versatile!

Robin WilliamsJanuary 13, 2026✓ Verified purchase

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. Read more

Works Perfect

JerimiaFebruary 1, 2026✓ Verified purchase

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. Read more

Works great

DanOctober 18, 2025✓ Verified purchase

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. Read more

Fast response

SwarFebruary 2, 2026✓ Verified purchase

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. Read more

Arrived with dead batteries

Frederick P. HerrmannFebruary 11, 2026✓ Verified purchase

"Batteries included" but it arrived with a pair of dead LR44s installed. Replaced with a pair of Duracell 357s and it seems fine now. As other reviewers have noted, the magnet is not so strong and might be disappointing if that's important to you. Read more

★★★★★

Klein is the last word in everything they do.

HankDecember 26, 2025✓ Verified purchase

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. Read more
