Product Description

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.

Applications:
Wind resource assessment, solar resource assessment, solar monitoring, meteorology and environmental monitoring.
