Reliable CO2 measurement starts with the right range for the task. This probe family gives users a choice between 0...5000 ppm and 0...10,000 ppm, making it suitable for applications that need carbon dioxide values in different concentration bands.
Both CO2 probes are complete with SICRAM module and operate from -20...+60 °C. That combination supports straightforward use with compatible measuring instruments and stable handling across changing ambient conditions.
For calibration work, the HD31.B3A adapter connects the HD31.B3 CO2 sensor to a nitrogen cylinder. The connecting tube is included, helping users prepare the calibration setup with the dedicated accessory.
The family includes two CO2 probe versions with different measuring ranges. The HD31.B3 covers 0...5000 ppm, while the HD31.B3-10 covers 0...10,000 ppm.
Both CO2 probes are complete with SICRAM module for use with compatible measuring instruments.
The CO2 probes are specified for operation from -20...+60 °C.
The HD31.B3A adapter is designed for calibration of the HD31.B3 CO2 sensor with a nitrogen cylinder. The connecting tube is included.
