Description
The SC75 CO2 Sensor can measure indoor CO2 concentrations in order to determine indoor air quality (IAQ). The SC75 offers a dual-mode power option, allowing the sensor to use an AC wall adapter for best performance, or up to 4 months operation using the built-in battery at a slower sample rate. By placing SC75 sensors in building spaces, ASHRAE IAQ performance can be easily monitored and verified.
