TESTO 405

The TESTO 405 is a pocket-sized thermal anemometer. It allows the measurement of air flow velocity, volume flow and temperature. TESTO 405 is ideal for measuring the flow in ducts or at duct openings or draughty windows. The anemometer features a permanently mounted telescope and enables to measure air flow, volumetric flow and air temperature. The measuring range for flow is between 0m/s to 10m/s with 0.01m/s resolution, volumetric flows are calculated up to 99,990m3/h. The extendible telescope (up to 300mm) makes the thermal anemometer particularly suitable for flow measurements in ventilation ducts. The illuminated display can be swivelled into various positions, ensuring that the readings can be read off comfortably. The duct bracket offers key practical advantages.
