Welch Allyn SureTemp Plus 690 Electronic Thermometer with Wall Mount and 9ft Oral Probe

The inspector did a very thorough assessment of my air conditioning system. I was particularly appreciative for his recommendation to clear the duct work. I don’t believe I had ever done that before.

Very accurate. Just as with old days mercury thermometers. Where the rule was to keep it under armpit (my preferred method) for >5 minutes. As it happens here the normal mode of operation tries to approximate the temperature in 10-15 seconds based on the temperature raise speed. Just like a drugstore cheap thermometer, maybe a bit more accurate. But then you can turn it in monitor mode, and see the temperature gradually stabilize for over 5 minutes to an absolutely accurate value. My difference between normal and monitor mode in 3 tries was from 0.0C to 0.3C (as usual, lower than the real/monitor temperature). Would be close enough for most purposes, but then again you never know when and by how much a little CPU will misjudge the temperature rise curve. So I always will end using the monitor mode.As expected, and this is why I was looking for this kind of a thermometer, even though it is 10 to 30 times more expensive than typical cheapo-crapo junk.

Way too expensive for personal use at best it’s a 50 dollar product they are just trying to sell you the name the thermometer works the way it should I work with them at my job but would never pay this much for one

The product was defective but requested refund and was granted fast. Great customer service!

This thermometer is perfect for home use if you need to watch your temperature. Readings are fast and very accurate. Although, its very expensive I believe it's worth the price.

as ordered - no problems

Excellent product, accurate.
