testo 425 - Thermal anemometer with flow probe
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.-
Temperature and flow measurement as well as volumetric flow calculation
-
Permanently attached extendible telescopic probe – maximum length 820 mm, diameter 7.5 mm
-
With single and multi-point averaging
-
Hold function, display of min/max value, Auto-off function
