BAPI, BA/BQP60X-B-C-B-X-XX-X, Quantum Prime VOC Air Quality Sensor, 10K-3 Thermistor, VOC 0 to 10V Output
Features:
- Achieves True Indoor Air Quality, Not Just CO2 Dilution
- Output is Correlated to a CO2 Value Allowing You to Ventilate Using ASHRAE's CO2-Based VRP Algorithm
Humans respirate Volatile Org-anic Compounds (VOCs) as well as CO2. The BAPI sensor is able to measure these VOCs and indicate 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. So using this sensor for Demand Controlled Ventilation is a way of achieving true indoor air quality, rather than 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.
