Air Quality
VOC Room Sensor, BAPI-Stat 3 Enclosure
Features & Options
- VOC Alone or Temperature and Humidity Combination
- Indicates Space Occupancy by Detecting Human-Generated VOCs
- Output is Correlated to a CO2 Value Allowing You to Ventilate Using ASHRAE’s CO2-Based VRP Algorithm
Humans respirate Volatile Organic 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. 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 on our website at www.bapihvac.com, or in the Application Notes at the end of this section of the catalog.)
The unit is available as a VOC sensor alone or as a combination temperature and humidity sensor. The optional display alternates between the measured values and is field adjustable between °F or °C. An optional three-color LED indicates “VOC Level” of Good, Fair or Poor.

BAPI’s VOC Duct Sensor samples duct air using an aspiration tube. Moving air from the duct enters the tube, is forced into the BAPI-Box enclosure and exits through the other half of the tube. As long as there is air movement in the duct, air is continuously exchanged. The Rough Service unit features a ventilated BAPI-Box and is ideal for rough service areas such as outdoor air plenums, equipment rooms, attics, green houses and warehouses.

CO2 Room Sensor, BAPI-Stat 3 Enclosure
Features & Options
- Automatic Barometric Pressure and Temperature Compensation
- Optional Temperature, Temperature Setpoint, Override and Humidity
- Optimized for Periodically Unoccupied or Continuously Occupied Areas
The BAPI CO2 Sensor is an accurate and reliable way of incorporating demand controlled ventilation into a building’s HVAC strategy. It measures the CO2 in a range of 0 to 2,000 ppm with a field selectable output of 0 to 5 or 0 to 10 VDC.
The Single Beam (ACD) unit has been optimized for periodically unoccupied areas and features automatic background calibration over a long time period to reduce drift. The Dual Channel (DCD) “24/7” unit has been optimized for continuously occupied areas and features a three-point calibration process for enhanced stability, accuracy and reliability.
Barometric pressure changes from altitude or weather patterns can affect CO2 sensors, even putting them outside of their specified accuracy. The BAPI unit has a built-in Barometric pressure sensor that continuously compensates the output for accurate readings despite the weather or altitude of the installation.
The unit can be ordered as CO2 alone, or with optional temp, temp setpoint, override and humidity. The large format display is easy to read and alternates between the measured values (CO2, Temperature or Humidity). The display is also field adjustable between °F or °C and all the displayed values may be turned on or off by an HVAC technician. Optional indication of CO2 level as “Good, Fair or Poor” is available as a three-color LED or as an arrow on the display for 0 to 2,000 ppp units.

Carbon Monoxide Sensor
Features & Options
- Field Replaceable Electrochemical Sensor
- Two Independent Alarm Contacts
- 2-Line, 16-Character LCD
- Field Selectable CO Ranges and Outputs
- Sensor Self-Test
BAPI’s Carbon Monoxide Sensor offers enhanced
electrochemical sensing with outstanding accuracy at
low concentrations.
The sensor has field selectable CO ranges of 0 to 100, 0 to 200, 0 to 300 and 0 to 500 ppm. It also has field selectable outputs of 0 to 5, 1 to 5, 0 to 10 and 2 to 10 VDC as well as a 3-wire 4 to 20 mA output. The LCD shows the CO reading in ppm and is backlight for 10 seconds after any button push.
Two independent SPDT alarm contacts switch at field selectable CO concentrations of 25, 35, 50, 100 and 200 ppm. A status LED is green when the measured CO is below the lowest relay setpoint. The LED turns red whenever an alarm relay is on.
An alarm timer holds the output relays on for a fixed time after the CO level has fallen below 80% of setpoint. This allows additional fan run time to be sure that the CO has been purged. Field selectable times of zero, one, five and 10 minutes are provided.
The sensor element is tested daily for proper operation. When the sensor element reaches its end of life, both relays turn on, the output is set to maximum and the status LED is yellow. Sensor elements last approximately 7 years and the sensor module is field replaceable.

CO2 Sensor Calibration Kit
Features & Options
- Calibrates All BAPI CO2 Room and Duct Sensors
- Verifies Proper Operation of All BAPI CO2 Room and Duct Sensors
- Logs CO2 Measurements
BAPI’s CO2 Sensor Calibration Kit verifies the proper operation and calibrates all of BAPI’s room and duct CO2 sensors.
Two calibration gas concentrations are required to perform a complete calibration*. Purchase the single point gas at a CO2 concentration of 400 to 800 ppm, and the span gas at 1,000 to 1,200 ppm. Only one regulator is required because it can be swapped between gas cylinders.
