The IceFree3 signal output is a variable amplitude sine wave, where frequency is proportional to wind speed. Patented off-axis correction minimizes errors in measuring up-slope or down-slope winds. The internal heater is powered by 24 VAC and allows for an operating temperature range of -40°C to 80°C (-40 °F to 176 °F). The optional 120/240 VAC to 24 VAC is available to step down 120/240 VAC grid power.

The IceFree3 Heated Anemometer comes with a 10 m potted cable that can be extended to your desired length in 10 meter increments up to 90 meters.
