The GASMAX IIx gas monitor delivers the latest in wireless toxic or combustible gas detection technology, reliability and ease of use.

Advanced electronics allows the GASMAX IIx to support any single GDS Corp electrochemical toxic or bridge-type catalytic bead, infrared or PID sensor. GDS Corp Smart Sensors enhance this capability by maintaining their own record of serial number, born-on date, initial calibration values, engineering units and more. Using this information, the GASMAX IIx constantly tracks sensor performance and calculates an estimate of sensor life remaining.

The highly visible backlit display and high intensity alarm LEDs constantly show alarm status, calibrated engineering values and programmable tag name; a trend screen shows alarm levels and the most recent 30 minute data values. An internal real-time clock and event log time-stamp calibration and alarm events for later review. A menu-driven operator interface using magnetic keys eliminates all analog potentiometers and allows complete setup and calibration without hazardous area declassification.

An internal 900Mhz or 2.4Ghz license- free spread-spectrum wireless modem allows the GASMAX IIx to transmit gas detection data to a remote host controller. Every 6 seconds, the GASMAX IIx samples the atmosphere and transmits a warning signal if the pre-programmed alarm level is exceeded. Under normal “no-gas” conditions the GASMAX IIx transmits a ‘keep-alive’ signal every five minutes to verify communications.

The GASMAX IIx is designed to communicate with the C1 Protector 8/16 channel controller / receiver or the C2 Quad Protector 4 channel controller / receiver. Both controllers are available with integrated 900Mhz or 2.4Ghz wireless modems.

The distance at which any wireless connection will operate reliably is dependent on many factors, including terrain, frequency, path length, interference from existing radio sources, combined antenna height, transmitter power and receiver sensitivity. For reliable communication, the system power margin (TX power + RX gain + Antenna gain - Path Loss) must exceed 20 dB. Range can be improved by increasing antenna height, using directional antennas or increasing transmitter power.
