VOC Room Sensor, BAPI-Stat “Quantum” Enclosure
Part Number: BA/BQX
Humans respirate Volatile Organic Compounds (VOCs) as well as CO2. The BAPI sensor measures these VOCs and indicates when a space is occupied just as well as a CO2 sensor.
The advantage of the VOC sensor is that it measures air contaminants from other sources besides respiration, such as building materials, cleaners, perfumes and furniture and carpet off-gassing. Using this sensor for Demand Controlled Ventilation then is a way of achieving true indoor air quality, rather than just CO2 dilution.
A further benefit is that it requires no additional work on your part. That’s because the sensor converts the VOC reading to a CO2 equivalent level. This lets you use ASHRAE’s CO2-based VRP schedule to ventilate. (More information on the CO2 equivalent output is available in the Application Notes tab below.)
The BAPI-Stat “Quantum” VOC Room Sensor features 0 to 5 VDC or 0 to 10 VDC output. The VOC level is indicated as “Good, Fair or Poor” by three green, yellow and red LEDs on the front of the unit.
