The ACR Systems IAQ Logger (SR-IAQ) 5-Channel (Temperature/Relative Humidity and External Temperature/Relative Humidity) Data Logger with 32 KB Memory records two leading indicators of indoor air quality: (1) temperature and (2) relative humidity (RH). The IAQ solution is ideal for those applications requiring long-term, close monitoring and recording.
Two (2) channels for temperature and/or RH (with ACR thermistor probes or ACR temp/RH probe)
