FACTORS AFFECTING THE CHOICE OF VOC SENSOR

+

PhotoIonisation (PID) VOC sensors PIDs respond to most VOCs except for small hydrocarbons such as methane, and for some halogenated compounds. Each VOC has a characteristic ionisation potential and the peak photon energy generated in a detector depends on the PID lamp used. For example, a Xenon lamp = eV, a Krypton lamp = eV and an Argon lamp = eV. Hence, the use of an argon …

BAPI’s VOC sensors provide that critical air quality information. The CO 2 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 CO 2 level of 0 to 2,000 ppm. This allows the sensor’s output to be used for ASHRAE’s CO 2based VRP ventilation schedule. Additional ...

D20 Using the BAPI VOC Sensor for Demand Controlled ...

+

BAPI’s VOC sensor offers the best of both worlds. It allows for ventilation based on occupancy as well as air contaminants. The BAPI unit does this because it has been optimized for DCV. Using a calibration algorithm, the sensor value is converted to an output with a high correlation to a CO2 level. This lets you use Ashrae’s more popular and straight forward occupanybased VRP schedule ...
