35-3001-05-02 IR Carbon Dioxide (CO2) 0-5000 ppm

The 35-3001 series is a compact sample draw detector assembly with a built-in pump that is powered from 24VDC. This unit features a NEMA 4X enclosure, making it dust, water and corrosion resistant. It also features a low flow alarm which warns of any obstructions or restrictions in the flow system. Combustibles, oxygen, and carbon dioxide versions are available with or without a 4-20 mA transmitter. H2S and CO versions both have 4-20mA outputs. The 35-3001 is also available in many dual sensor configurations.

The 35-3001 is capable of single person calibrations and remote sampling at up to 5,000 ft. from a controller, and interfacing to any RKI or third party control system (utilizing a 4-20 mA feedback signal).
