The sensor will be sensitive to a wide variety of VOCs, rather than to one specific individual VOC. How does the change in resistance become a TVOC reading in ppb? Although similar, different VOCs will have slightly different reactions the same increase in formaldehyde and in ethanol might not lead to the exact same change in resistance on the sensor.

Thus, in cases where VOCs are viewed as a measurement object, each measurement project must be able to deal with all possible morphologies of each VOC sample. For this reason, we have developed a continuous VOCsinwater sampling column for the measurement of VOCs in water. This column, in combination with the PID or gas chromatograph, makes it possible to support all sorts of application ...

The VOC sensor eliminates the need for frequent manual calibration by providing a relative measurement and using an Automatic Baseline Correction (ABC) logic algorithm. With ABC selfcorrection, the sensor constantly adjusts the 450 ppm baseline (outside air) to eliminate any sensor drift. The logic drives the sensor to quickly reduce the baseline when a time of low measurement is sensed.

Measure to manage The Fidelix FXWMBUSE2VOC room VOC, temperature, and humidity sensor is a plugandplay room VOC, temperature, and humidity transmitter.
