Description

The AST-IS3 transmitter contains a non-dispersive, infrared CO2 sensor housed in an industrial style, water tight enclosure with built in rubber gaskets ideal for installation in ventilation ducts.

It is low maintenance and a key component for climate control of buildings and different ventilation strategies. It is designed to be connected directly to a BAS or Controller. It requires 24 VDC / VAC nominal voltage power, has 4 - 20 mA or 0 - 10 VDC linear output signals and offers a standard 0 - 2,000 ppm gas monitoring range.
