Used for years
I have used this model for years as a contractor and it seems to yield consistent results when compared with the weather reporting stations within a few percentage points. The accuracy seems to be a bit less in colder temps ,but for the most part a very reliable instrument.

Very good
I had one years ago and lost it, needed another one and decided to buy it again because of how much I liked it. Perfect for reading humidity, dry bulb and wet bulb temps.

Fine machine for the price!
It is a very user friendly machine and I like the instant readout for the humidity. It seems to read colder when I first bring it into a warm room; like the head has to warm up before it really reads the right temp. But I've not used it that much to see what's what.

Great meter
Excellent meter and quite accurate, I have found it accurate to +/- 0.2F. Uses a Sensiron SHT2x sensor, so it's quite accurate by design.Wireless Serial reader and PC application are very helpful for remote reading.Like any meter however it does need a little time to acclimate to the climate it's in, you can't take it from somewhere warm to cold or vise versa and expect an instant correct read.

Exactly as described.
I purchased a new one because last one was not accurate at all. This one is so much better than the old one. It is incredible accurate and fast. Just give it a couple min to get the measurement then your good to go.

Very pleased with it
Very pleased with it, have used Amprobe tools before in my work and it is a good brand name. This is a must have for checking HVAC especially when charging home systems with out TXVs and you need WBT, RH in addition to DBT.
