TM-402~404
Air Velocity Meter

  • 30mm 6 plastics vane
  • Light air response 0.4m/s.
  • Air flow calculates function

APPLICATION

TM-41X series measures air speed, temperature and humidity. It is ideal for spot measurements at air outlets on account of its 30mm vane. In addition to air speed and temperature, also measures air moisture and absolute pressure. In this way, air conditions can be reliably checked
