The CL2-A1 Alphasense Chlorine Gas Sensor is a 20mm diameter sensor, designed to monitor CL2 concentrations to prevent injury to those working around the gases presence. CL2 sensors are available in a wide range of formats and are suitable for use in both fixed and portable gas detection.

The CL2 range provides OEMs with reliable sensing for use in a number of high volume applications. Strong signal levels combined with low zero current allows resolution to 20ppb and an operating range from +0 to 20ppm. 

Chlorine gas sensors are also commonly used due to their electrolyte leak-free guarantee and reliable long-term detection performance. The leakproof housing is molded with a color coded top for ease of identification.

    Tube cap adapters easily convert 20mm standard gas sensors from diffusion to sampling sensors. Molded polymer grips sensor for easy fit and removal while maintaining a good seal.

    Micro-Pump Kit includes all the tools you need to urilize the tube-cap adapters as part of a sampling sensor system.

    Nafion tubing is a highly selective, semi-permeable membrane to water vapor. If gases inside Nafion tubing are wetter than gases surrounding the tubing, drying will occur. If the surrounding gases are wetter, humidification will occur.

    Micro gas sampling pumps provide a constant flow of air across the sensor with a tube cap - perfect for bench-top testing of sensors for closed-loop sampling applications.

    Sensor Pin Sockets - Manufacturers do not recommend soldering to the pins. Pin sockets can be purchased from Andon distributors. Click here to search for your sensor's socket. Select the brand PDF, find your sensor, then search for the Andon part number for your sensor's socket.
