Infrared CO2 sensor

Cal Sensors, Inc.

Cal Sensors announces the global launch of the IRCO2, an infrared CO2 sensor for HVAC applications. Designed to meet the challenging accuracy and reliability requirements of Demand Controlled Ventilation systems (DCVs), the IRCO2 combines superior sensitivity and reliability with lower costs and power consumption.

Cal Sensors' IRCO2 sensor applies the latest in non-dispersive infrared (NDIR) technologies. The optical path consists of a state-of-the-art emitter and detector that optimize the signal to noise performance while minimizing costs. Unlike traditional CO2 sensors that produce a signal by reacting with the gas, thus degrading over time, NDIR sensors generate a signal passively, by measuring the absorption of infrared light through the gas. Consequently, the infrared system eliminates degradation concerns, reduces maintenance, and provides accurate measurements more reliably.

Cal Sensors can support prototyping to high volume manufacturing requests with lead times depending on quantities desired.

The IRCO2 was first introduced at the SPIE Photonics West 2013 exhibit held February 2-7, 2013 in San Francisco, California.
