RKI RI-215D Offers

The RKI RI-215D IR Sample Draw Air Quality Monitor is widely used in the measurement and control of CO2 levels in a variety of applications where CO2 monitoring or detection is required. A highly accurate, RKI non-dispersive infrared absorption sensor is used to provide direct measurements through sample draw monitors and activate alarms or control ventilation systems based on preset CO2 levels. Each model provides a digital readout in parts per million of CO2 providing precise measurement and direct visual indication of gas levels. A 4 to 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 to 2,000 ppm (ASHRAE 1969 IAQ max PEL), 0 to 5,000 ppm (leak detection of CO2 storage tanks) and 0 to 9,999 ppm. The RI-215D with sample drawing pump runs on 115 VAC or 220 VAC. It is designed for indoor use only and supplied in a NEMA 12 enclosure that is easily accessible for calibration, service and continuous monitoring.
