Applications for the E2638-CO2 include office and industrial buildings, greenhouses, underground garages, heating systems or other enclosed spaces where toxic carbon dioxide concentrations may accumulate.

The instrument uses a fully calibrated and temperature compensated photoacoustic gas sensor with excellent repeatability, stability and long lifetime.

The sensor can be used universally via two analog outputs and a digital RS485 interface with the industry standard Modbus RTU protocol.
