Description

VOC Pro Datasheet [PDF]

VOC Pro Operator’s Manual [PDF]

The VOC Pro Series Gas Detector is a versatile assembly that uses a PID sensor to detect a variety of gases. Wired power (12 to 35 VDC) with 4-20 mA analog and RS-485 Modbus outputs are standard. Magnetic switches allow for non-intrusive calibration while in the field as well as full system settings and diagnostics.

The VOC Pro represents the latest leading edge technology in fixed gas detection today.

PID Sensor Response Factors for VOCs

Photoionization detectors are calibrated using isobutylene, but PID is a broadband VOC detection technique, with a sensitivity that differs for each VOC. If you know what VOC you are detecting, then the table below will allow you to calculate the concentration for your specific VOC. Remember, these are approximate values, so for best accuracy you should calibrate with the relevant VOC. Multiply the indicated concentration by the appropriate Relative Response value to provide an estimate of actual VOC concentration. Download a PDF of PID Response Chart.
