DTH35, Digital Psychrometer with Enthalpy

The temperature sensor seems OK, but the humidity sensor worked for just one day. It locked at 99.9 and never went down. We could not even complete the measurements on our 30 chambers. I was using it for highly humid and probably saturated conditions, but expected the sensor to dry out and go to ambient after readings. It was a waste of money.

I use it every day and it's easy to use and the probe isn't overly big, so it fits in test holes with ease.

Excellent product for wet bulb & temperature measurements

You can calculate unit BTU output knowing the wet bulb with easy digital probe that fits in your tool bag.

For the cost a great value digital psychrometer. The ability to measure enthalpy in BTU/lb sets it apart especially cost-compared to other digital psychrometers. Only negative so far is the plastic body and probe. Not sure how well would survive a fall of 5-7 ft from ductwork. Although has a good magnet on the back, cannot use when probe inserted in ductwork (probe length is very good comparatively). I need to affix a hook or key ring on the device to allow tying string or wire so can fasten to something when working w/ device on ladders or step stools.
