VOC SENSOR CO2.

Using the BAPI VOC Sensor for Demand Controlled ...

The VOC and CO2 sensors are located next to each other in the dining room near the kitchen entrance. The open percentage of the outdoor air damper for this area is controlled by the VOC sensor output through a PID control loop from 5 am to 2 pm on weekdays when the space is considered “occupied”. The outside air damper is closed during the unoccupied period, and ventilation is accomplished ...

Kele KCOC Series | Combination Carbon Monoxide Sensor with ...

The Kele KCOC Series Combination Carbon Monoxide Sensors pair a CO sensor with a CO2, RH, or VOC sensor in the same enclosure-reducing installation time and space required. The unit provides visual indication and analog output of CO levels in enclosed spaces such as schools, offices, malls, and theaters. The analog output is available for 0-10V or 4-20 mA and is scaled from 0-200 ppm of CO.

Duct sensor CO₂ / VOC / CO₂+VOC mix

This VOC sensor automatically compensates the decrease in sensitivity by dynamic auto-calibration. The reference level of air quality is derived from the ambient conditions over a 72h period. The lowest reading within this 72h time period will be used as reference level, representing the “clean and fresh air level”.

CO2 vs. VOC Sensors for IAQ - What's the Difference

2012-01-13· Unlike a CO2 sensor, a VOC sensor cannot indicate the rate of ventilation needed, only the level of VOCs in the air. It also cannot necessarily indicate whether safe or harmful concentrations of VOC contaminants are present. It can indicate a general change in the concentration of contaminants. This makes air quality sensors a better solution in applications where unusual, non-occupant-related ...
