PRODUCT DESCRIPTION
The TH-8902 is a handheld meter for airflow, temperature, humidity, dew point, and wet-bulb measurement. Its 50 mm vane sensor captures air velocity directly, while the built-in thermo-hygrometer derives dew point and wet-bulb values on the spot — five parameters from a single pocket instrument.
An 8-point memory with max/min/average recall supports quick surveys, and the RS232 interface allows readings to be transferred for logging and reports. Power comes from 4 AAA batteries or a 9V supply for bench use.
