RKI Instruments RI-85 Portable Infrared CO2 Gas Monitor
Portable and compact, the RI-85 Portable Infrared CO2 Gas Monitor provides fast and accurate gas detection. The RI-85 uses a microprocessor controlled sensor to accurately determine instant, peak and average CO2 values at levels between 0 and 10,000 ppm. Use RKI gas monitors for indoor air quality monitoring, health and safety compliance in factories and other facilities, fire equipment leak inspections and more. The R085 uses a NDIR sensor to provide 90% accurate readings within 15 seconds using the built-in sampling pump.
