    Hot ball probe (Ø 7.5 mm) - for flow, temperature and humidity

    0635 1540
  1. 3 functions in 1 probe: measurement of flow, temperature and humidity
  2. Measures temperatures up to +70 °C
  3. Flow measuring range: 0 to +10 m/s 
    4. The hot ball probe (in conjunction with the appropriate measuring instrument) is ideal for determining flow velocity as well as temperature and humidity in ventilation ducts.
    Use the hot ball probe (thermal anemometer) to determine flow velocity and volume flow in ventilation ducts. It is particularly suitable for low flow velocities of up to +10 m/s. The probe can also measure temperature and humidity simultaneously.

    Hot ball probe (Ø 7.5 mm).
    Note: you need a plug-in head cable (0430 0143) for this probe.
