(Specify Volatile Compound)

PID (Photo Ionization Detection) technology detects a wide variety of organic and some inorganic gases in ambient air, generally low concentration of complex hydrocarbon molecules; this allows an early warning for presence of these gases in concentrations not seen by conventional LEL detectors.

The GASMAX II PID Gas Monitor is a fixed point explosion-proof gas transmitter utilizing a photoionization detector (PID) to detect small concentrations of volatile organic compounds (VOC) such as benzene, toluene, xylene and chlorinated hydrocarbons.

The GASMAX II operates from 10 to 30 VDC and provides both 4-20mA analog and (optional) MODBUS® digital output. Calibrated engineering-units values are displayed on a large, backlit LCD. Standard features include two level alarm setpoints, fault alarm, LED indicators, non-intrusive calibration and a Smart Sensor interface for locally mounted sensors. Isolated 4-20mA output and alarm relays are available.



The PID Smart Sensor is available in two ranges, High Range (0-2000 ppm) and Low Range (0-20 ppm) that must be specified when ordering. The PID sensor is fitted with a replaceable 10.6 eV light source designed to ionize the most commonly found VOCs while at the same time remaining insensitive to changes in humidity, oxygen or CO2 levels. Any compound with an ionization potential (IP) of 10.6 or less can be detected with the GASMAX II / PID monitor.

In addition to dual 4-20mA current loop outputs, an RS-485 two-wire MODBUS® interface and three optional 5A relays are available to communicate with controllers or local alarm indicators.

Operator interface is via a menu-driven magnetic keypad, allowing complete setup and calibration without hazardous area declassification.

The GASMAX II maintains a record of sensor calibration data that provides an estimate of sensor life remaining. During each post-calibration purge delay, the GASMAX II can be programmed to transmit this data on the 4-20mA output.

Locally connected Smart Sensors enhance this capability by maintaining their own electronic record of serial number,born-on date, initial calibration values, engineering units and other data, ensuring the most accurate measurement and alarming capability available today.
