    CO₂ probe head including temperature and humidity sensor

    0632 1550
  1. Intuitive: parallel determination of CO₂ concentration, humidity and air temperature in indoor areas, including long-term measurement
  2. Precise: absolute pressure compensation, calculation of wet bulb temperature, dew point and absolute humidity
  3. Convenient: probe head is easy to attach to the universal handle with Bluetooth or cable (available to order separately)
  4. Intelligent calibration concept: only send in the probe head for calibration
  5. More applications, less equipment: if you already own one of our probes with a universal handle, you can easily expand your portfolio of probes with the CO₂ probe head.

    CO2 probe head including temperature and humidity sensor and calibration protocol.

    Please do not use the probe head in condensing atmospheres. For continuous application in high-humidity ranges
        > 80% RH at ≤ 30 °C for > 12 h
        > 60% RH at > 30 °C for > 12 h
