Specification :

Measure air velocity, temperature, and humidity in a pocket sized meter
Simultaneously view air velocity/ temperature or humidity/ temperature
Measure external temperatures with type K thermocouple probe ( order separately)
This pocket thermoanemometer is ideal for air duct and ventilation measurements. The integral, low-friction vane improves accuracy of air velocity measurement. When powered off, the meter defaults to the last function used. Features include data hold, min/ max readings, selectable ° F/ ° C readings, auto shutoff, low-battery, and overrange indication.
Whats included: wrist strap and 9 V battery.
