    2. Efficient, robust NTC air probe

    Robust air temperature probe (NTC)

    0613 1712
  1. NTC temperature sensor
  2. High level of accuracy of up to ±0.2 °C 
  3. Short response time thanks to the exposed sensor
  4. Measuring range: -50 to +125 °C
    5. Use the robust air temperature probe with exposed sensor (NTC) to measure air temperature with a short response time. It can be connected to a wide range of measuring instruments.
    Fast, robust and easy to use: simply hold the air temperature probe in the environment being measured – and, thanks to the exposed sensor in the probe shaft, you will obtain the air temperature value after only a short response time. The measurement result can be optimized by moving the probe through the air at approx. 1.5 m/s. 

    Robust air temperature probe (NTC) with fixed cable 1.2 m.
