Designed to detect toxic gases, oxygen and refrigerant gases, the CTX 300 uses a sensor for CO2 detection over three different ranges: 0 to 5000ppm, 0 to 5% vol. and 0 to 100% vol.
The output signal is open-path over the three measurement ranges, without the need for a supplementary processing card. A version with a display is also available, and accessories for the standard CTX 300 are compatible with the CTX 300 CO2. The device also features removable filters which can be changed without having to open the housing, which has an IP54 rated.
For versions without displays, the operating temperature range is from -40 to 50°C, allowing for applications in extreme cold areas. For versions with a display the operating temperature range is -20 to 50°C.
