Thermal anemometers without smartphone operation

testo 425 - Thermal Anemometer

Order-Nr. 0560 4251

The functional testing of ventilation and air conditioning systems includes monitoring the flow speed in ventilation ducts. If the air flow velocity and volumetric flow are not set correctly, the room air quality may suffer. The testo 425 thermal anemometer measures the flow speed and automatically calculates the volumetric flow.

3 in 1 Measurements Temperature, air flow & volumetric flow calcualtion
Extendable telescopic probe
Single & multi-point averaging
Hold button to freeze readings
