The quality of the air that we breathe is essential to our health and knowing the air quality level is the first step to improving it. BAPI’s VOC sensors provide that critical air quality information.

The CO2 equivalent (CO2e) units combine the benefits of VOC sensors and the common application of CO2 sensors into one unit. It provides a VOC reading that correlates to a typical indoor CO2 level of 0 to 2,000 ppm. This allows the sensor’s output to be used for ASHRAE’s CO2-based VRP ventilation schedule. CO2e units come with 3 VOC level status LEDs on the face of the unit.

The total VOC (TVOC) units provide a VOC reading that is the total concentration of all VOCs present in the space within a range of 0 to 2,500 ppb. This is often needed to meet 3rd party building certifications that require separate CO2 and VOC readings. TVOC units do not have status LEDs on the face of the unit.

(Additional information on VOCs and using the CO2e units in your ventilation strategy is available in the “Documents” tab at right.)

The Duct unit uses an aspiration tube, while the Rough Service unit uses a ventilated BAPI-Box and is ideal for areas such as outdoor air plenums, equipment rooms, green houses and warehouses.
