High Accuracy Temperature, Humidity & IAQ Monitor CDM77232

IAQ monitoring and ventilation control. Ideal for monitoring indoor air quality of houses, offices, classrooms, factories, hospitals and hotels. Includes relay for activating a ventilation system.

High Accuracy Temperature, Humidity & IAQ Monitor Features:

  • Measures ambient temperature, relative humidity (RH), dew point and wet bulb temperatures, and CO2 level
  • Backlit LCD displays ambient temperature, RH and CO2 level on separate readouts
  • Uses stable non-dispersive infrared (NDIR) sensor to measure CO2
  • Calculates, periodically updates and displays 8-hr. time-weighted average (TWA) of CO2 exposure and 15-minute short-term exposure limit (STEL)
  • Adjustable Hi and Lo audible/visual CO2 alarm levels
  • Relay activates/cancels output signal when CO2 level exceeds Hi alarm level/falls below Lo alarm level
  • Min/Max memory + data hold
  • RS-232 output jack; optional ASFTKIT PC interface/data logging kit includes RS-232 to USB adaptor
  • 33% HR33LJ and 75% HR75LJ reference salts are available to calibrate relative humidity (RH) measurement in the field
  • Auto power off (can be disabled for calibration)
  • Wall or desktop mount
