General Tools - CDM77232 - High Accuracy Output Relay Humidity/Temperature/IAQ Meter

  • Item #: 4939600
  • MFR SKU: CDM77232
  • Measures ambient temperature , relative humidity (RH) , dew point and wet bulb temperatures , and CO 2 level
  • The backlit LCD displays ambient temperature , RH and CO 2 level on separate readouts
  • Uses a stable , non-dispersive infrared (NDIR) sensor to measure CO 2
  • Calculates , periodically updates and displays an 8-hr. time-weighted average (TWA) of CO 2 exposure and a 15-minute short-term exposure limit (STEL)
  • Adjustable Hi and Lo audible/visual CO 2 alarm levels
  • The output relay activates/cancels its signal when the CO 2 level exceeds the preset Hi alarm level or falls below the preset Lo alarm level
