UEi Test Instruments PDT650 Folding Pocket Digital Thermometer,Yellow

I have to say these things are pretty dam good. I bought mine 10 years ago and they are still working great!

Easy to read/use while repairing or checking to determine if HVAC unit is running correctly correctly. Can check ambient temps easily, room to room, by holding on flat surface (or held in hand) verifying for owner or tenant of building whether or not service is warranted. Depending on type of heat source, different rooms can fluctuate by quite a bit. This thermometer is perfect for this type of application.

The media could not be loaded. Get more than one, it’s easy to lose, and good to have extras for getting multiple simultaneous temperature readings at different locations. I’ve never had one stop working, and that’s saying something since I’m a savage at handling tools. Works well at reading the temperature. Magnet back makes it easy to stick to registers. Battery lasts very long time and is easy to replace.

I use this thermometer frequently on commercial hvac. It's accurate, reliable, and the price is better than the other thermometer on the market. The only downfall of this thermometer is it takes time for the temp to read. For example if the temperature I'm reading is 110F, it will take about 15 seconds to from 75 to 110F. I've used feildpiece thermometer and that is almost instantly but the price of those thermometer is more than double. Battery life is great, I've used it for about 6 months and still on the original battery. Would I buy this again? Yes, this is my 3rd one as people steal them and I've left one on a job site.

Compact and convenient to use.

Great thermometer for an HVAC technician. Quicker response than most.

fast ship, accurate listing

I ordered one of these which was shipped via UPS. UPS did not deliver to the correct location, resulting in me not receiving it. I contacted the seller and they shipped me a replacement the next day via FedEx. I got it with no problem, and it works great!
