IAQ Monitor Temperature, Humidity, Carbon Dioxide Alarm
High Accuracy Temperature, Humidity & IAQ Monitor
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
