The body is made of high quality anodized aluminium and the cups are made of resistant polycarbonate and supplied with a factory calibration with wind speeds between 4-16 m/s in accordance with Measnet recommendations. The anemometer can be supplied with a Measnet calibration.

Benefits:

Individual factory wind tunnel calibration 4-16 m/s (Measnet recommended measurement range)
The K620A anemometer is a cost-effective sensor
Corrosion resistant anodized aluminium
Resistant injection molded polycarbonate cups
Manufactured in the European Union
Highly resistant ball bearings
Easy assembly plug
Low level AC sine wave output signal (no power consumption)
Optional three-per-box packaging. Ensures safe and cost-effective transportation.

It is designed for mounting on 25 mm (or 1’’) diameter tube.
