RKI Instruments, RI-215 Series, Infrared CO2 Gas Detector

From RKI Instruments,

The RI-215 Series, Infrared CO2 monitor. Widely used for measurement and control of CO2 levels in a variety of applications where CO2 monitoring and detection is required. Highly accurate, RKI's non-dispersive infrared absorption sensor is used to provide direct measurements through diffusion or sample draw monitors, and activate alarms or control ventilation systems based on preset CO2 levels. 

Providing a digital readout in parts per million of CO2 for precise measurements 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:

1. 0 - 2,000 ppm (ASHRAE 1969 IAQ max PEL)
   
2. 0 - 5,000 ppm (leak detection of CO2 storage tanks)
   
3. 0 - 9,999 ppm.
   

The RI-215A runs on 24 VAC or 24 VDC and the RI-215D with sample drawing pump runs on 115 VAC or 220 VAC. Each are designed for indoor use only and supplied in a NEMA 12 enclosure that is easily accessible for calibration, service, and continuous monitoring. RKI offers additional monitors with higher measurement levels in portable or installation applications. Please contact an RKI authorized representative for more information on other CO2 monitors available.
