Product Description

The Amprobe TH-1 relative humidity (RH) and temperature meter simultaneously measures relative humidity, dew point, and wet- and dry-bulb temperature to provide dual-scale readings in F and C, and is used for HVAC, indoor air quality, and environmental applications. The capacitive humidity sensor measures RH from 0 to 100 percent. The extended probe has a cover to protect the sensor when taking measurements inside ducts. The meter has minimum, maximum, and hold functions for recording data, and relative zero functionality stores reference points. It requires one 9V battery (included), and includes a carrying bag, and instructions.

The first one did not respond when I installed the battery.No display....nothing. The second one also did absolutely nothing. The THIRD one did absolutely when installing the battery. Alll the batteries, (3 volts), were good.....(3.255 volts to 3.256 volts). All three of the TH-1's were defective and did nothing when energized. The displays did not turn on or even blink!

I bought this in July and used if for maybe 3 months. I have trouble getting it to turn on. I love the size, fits comfortably in my cargo pocket. I am shopping for a new one because I'm afraid It won't last much longer. Feels very cheaply made. Should be priced at $15 instead of nearly $70
