Alphasense Chlorine gas sensors operate using proven fuel cell technology. CL2-B1 Chlorine Sensor size: 32mmdiameter package, the best choice for fixed site application The Cl2 range provides OEMs with reliable sensors 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. The sensors are suitable for inclusion in fixed installation sensing heads and portable safety instruments. These sensors have improved transient response to humidity changes compared to competitors’ equivalent sensors. The Cl2 sensors offer our electrolyte leak-free guarantee and reliable long-term detection performance. The leakproof housing is moulded with a colour coded top for ease of identification. Note: The graphic of this sensor is an example only and sensor cap/body colour may vary depending upon gas sensor type ordered or manufacturing modification.
