The GASMAX ECx wireless gas monitor delivers the latest in toxic gas detection technology, reliability and ease of use. The GASMAX / ECx is designed for use in hazardous or explosion proof installations.

Wide Variety of Available Sensors

The GASMAX ECx support all GDS Corp toxic sensors; in addition, 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 ECx constantly tracks sensor performance and calculates an estimate of sensor life remaining.

Advanced User Interface

The highly visible display and alarm LEDs constantly show status, calibrated engineering values and a 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.

Fully Integrated Wireless Solution

An internal D-cell lithium battery and 900Mhz or 2.4Ghz license-free spread- spectrum wireless modem provide up to six months of continuous operation in typical applications. Every 6 seconds, the GASMAX ECx samples the atmosphere and transmits a warning signal if the pre-programmed alarm level is exceeded. Under normal conditions the GASMAX ECx transmits a ‘keep-alive’ signal periodically to verify communications and advise the controller if the battery is low. Host Controllers

The GASMAX ECx is designed to operate with the C1 Protector 8/16 channel controller / receiver, the C2 Quad Protector 4 channel controller / receiver or the C64 Protector multi-channel controller. Controllers are available with integrated 900Mhz or 2.4Ghz wireless modems.

  • Graphic display shows values, units, trend graph, alarm levels
  • Supports both local and remote sensors for easy installation
  • Non-intrusive, prompted calibration with programmable cal gas
  • Power-up and post-calibration delays eliminate false alarms
  • 900Mhz (US) or 2.4Ghz (worldwide) wireless modems available
  • Security settings to lock critical parameters
  • Auto-recognition of Smart Sensors uploads calibration data & more
  • Fault supervision circuitry detects failed sensor & transmits warning
  • Setup in hazardous area requires only simple magnetic wand
  • Typical > 1 mile range with local ‘whip’ antenna (900Mhz)
  • For combustible applications, see the GASMAX IIx gas monitor
  • Manufactured in USA
Determining Wireless Communications Range

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. Contact GDS Corp for more information.
