testo 405 – Thermal anemometer

Use the testo 405 thermal anemometer to measure air velocity, volumetric flow and air temperature. It is suitable for carrying out quick check measurements in ventilation ducts and for measuring the air velocity in rooms, e.g. at draughty windows.

Product benefits:

  • Measurement of air velocity, volumetric flow and air temperature
  • For measurements in ventilation ducts and in rooms
  • Particularly precise in the range between 0 and 2 m/s
  • Telescope extendible to 300 mm

Broj artikla: 0560 4053.

If, in your capacity as an HVAC engineer, you carry out fast check measurements in ventilation ducts or in rooms, then our testo 405 thermal anemometer is a must-have. The anemometer features a permanently mounted telescope and enables you to measure air flow, volumetric flow and air temperature. The measuring range for flow is between 0 to 10 m/s, volumetric flows are calculated up to 99,990 m3/h.
