RI-215A

The RI-215A is a wall-mounted IR CO2 monitor for measurement and control of CO2 levels in fixed location applications. A non-dispersive infrared absorption sensor is used to provide direct measurements through diffusion, and to activate alarms or control ventilation systems based on preset CO2 levels. The RI-215A provides a digital readout in parts per million of CO2 providing precise measurement and direct visual indication of gas levels. A 4-20 mA output is provided to send a signal to a fire panel or other PLC system and a relay is available to trip an alarm or activate a ventilation system. Three levels of measurement are provided: 0-2,000 ppm (ASHRAE 1969 IAQ max PEL), 0-5,000 ppm (leak detection of CO2 storage tanks) and 0-9,999 ppm. The RI-215A runs on 24 VAC or 24 VDC and is designed for indoor use only and supplied in a NEMA 12 enclosure that is accessible for calibration, service, and continuous monitoring.
