testo 405 – hot wire anemometer

If you want to make quick control measurements in ventilation ducts or in rooms, the testo 405 hot wire anemometer is the perfect instrument. The anemometer has a permanently mounted extendable telescopic probe and can measure air velocity, air flow and air temperature and is particularly suitable for flow measurements in ventilation ducts. The air velocity measurement range is between 0 and 10 m/s, the air flow is calculated up to 99,990 m³/h. Since the testo 405 hot-wire anemometer measures particularly accurately in the range of 0 to 2 m/s, you can also use it to measure air speeds in rooms such as those in the city. drafts at windows and doors, etc.

Advantages of testo 405

  • Measures air speed and temperature and calculates airflow
  • For measurement in ventilation ducts and in rooms
  • Especially accurate in the range between 0 and 2 m/s
