AST-IS transmitter contains an infrared sensor for accurate, reliable carbon dioxide (CO2) detection.

AST-IS transmitter convert the raw signal from a sensor into a useful output that can be sent to a controller or building automation system.

Standard enclosure is an attractive PVC office mount for indoor use. Optional duct mount, LCD digital display, relay, IP54 enclosure, and temperature sensor are available.

AST-IS transmitter feature 4 - 20 mA or 0 - 10 VDC linear output signals, low 24 VDC / VAC nominal voltage, standard 0 - 2,000 ppm range and 0 - 4% volume available for winery applications, and CE certification.

Lifetime calibration. Field calibration not required.
