Model SA2-VOC-11.7 (VOLATILE ORGANIC COMPOUNDS (11.7 EV))

VOC Detection Smart Sensor Module - 11.7 eV Photoionization Detector (PID)

Model SA2-VOC-11.7 smart sensor modules are designed to detect and monitor volatile organic compounds in ambient air with an ionization potential of 11.7 eV or below. The modules consist of a photoionization gas detection sensor and a micro-processor-based signal conditioning circuit. The signal conditioning circuit includes embedded temperature compensation and advanced detection analytics. Both are housed in a metallic enclosure fitted with gold plated connecting pins.

Environmental Data / Compensation

"The Smart Sensor Module" is factory programmed for a specific range of sensitivity. On power up, gas type, measurement range, and previous zero and span calibration data points are read by the transmitter, facilitating a fully automated startup. When used with any Safeguard Analytics gas detection transmitter, calibration may be performed on site or remotely, and the module transported to the point of installation pre-calibrated and ready for operation.
