Sauermann Kimo K-Si-VV3 - A Rotating Vane Anemometer for HVAC The Sauermann Kimo K-Si-VV3 is a rotating vane anemometer that measures air velocity, airflow and temperature simultaneously, displaying all three on a two-line backlit LCD. A 2m cable connects the vane probe to the instrument body, so it can be positioned inside ducts and ceiling diffusers without having to move or reposition the main unit. The vane covers a velocity range of 0.40 to 30.00 m/s and an airflow range of 0.00 to 9,999.00 m³/h, with a temperature range of -10.00°C to 60.00°C. The housing is IP54 rated, giving it protection against dust and water splash for use in plant rooms and other on-site conditions rather than office-only environments. Battery life is rated at 120 hours from three AAA alkaline batteries, and a magnetic backing lets it be fixed to any metal surface for
