CO₂ probe head including temperature and humidity sensor
0632 1550CO₂ probe head including temperature and humidity sensor
0632 1550Intuitive: parallel determination of CO₂ concentration, humidity and air temperature in indoor areas, including long-term measurement
Precise: absolute pressure compensation, calculation of wet bulb temperature, dew point and absolute humidity
Convenient: probe head is easy to attach to the universal handle with Bluetooth or cable (available to order separately)
Intelligent calibration concept: only send in the probe head for calibration
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.
