VOC Room Sensor Installation and Operation Instructions

Humans exhale Volatile Organic Compounds (VOCs) as well as CO 2. The BAPI sensor is able to measure these VOCs, therefore it is as good an indicator of space occupancy as a CO 2 sensor. The BAPI Sensor is different from other VOC sensors because it has been optimized for Demand Controlled Ventilation (DCV). Using a calibration algorithm, the sensor value is converted to an output with a high ...
