SAUERMANN SI-VV3 PROPELLER THERMO-ANEMOMETER SPEED AND AIR FLOW METER

The Sauermann SI-VV3 is a portable vane thermo-anemometer designed to accurately measure air velocity, flow rate, and temperature in HVAC, ventilation, and duct systems. Equipped with a large vane probe with a 2-meter cable, it supports direct reading on a backlit LCD display and data transmission via Bluetooth to smartphones and tablets via the free Si-HVACR app.

The air flow rate is automatically calculated by the app based on the selected surface area, allowing for a comprehensive analysis of environmental conditions.
