Description

This Model RI-85 is a compact, lightweight portable CO2 monitor with an Infrared (NDIR) type sensor. This sensor provides fast and accurate detection of CO2 levels from 0 to 10,000 ppm. An internal pump is utilized for continual sampling, and the unit operated for 12 hours from one set of batteries. Microprocessor control provides average readings over a selected time period, and also can display the peak value detected.

Application

  • Indoor air quality CO2 level testing
  • Safe CO2 breathing levels in plants or factories
  • Leak checking on CO2 fire extinguisher equipment
  • Check before intering after CO2 extinguisher use.
  • Exhaust gas leak from combustion appliances in homes or plants
