The GASMAX EC single channel gas monitor for toxic or oxygen deficiency ap- plications delivers the latest in loop-pow- ered gas detection technology, reliability and ease of use.

Wide Variety of Available Sensors

The GASMAX EC support all GDS Corp toxic sensors, including oxygen, hydrogen sulfide, chlorine, carbon monoxide and more. In addition, GDS Corp Smart Sen- sors enhance this capability by maintain- ing their own record of serial number, born-on date, initial calibration values, engineering units and more. Using this information, the GASMAX EC constantly tracks sensor performance and calculates an estimate of sensor life remaining. Built-in fault detection circuity constantly monitors the sensor for correct operation.

Advanced User Interface

The highly visible graphic display and flashing alarm LEDs constantly show alarm status, calibrated engineering values and a programmable tag name, plus a trend screen shows alarm levels and a graph of the most recent 30 minutes.

An internal real-time clock and event log time-stamp up to 300 calibration and alarm events for later review. Taking advantage of the high-resolution graphic display, an easy-to-use menu-driven operator interface using magnetic keys eliminates all analog potentiometers and allows complete setup and calibration without hazardous area declassification.

Three operational levels of security al- low the GASMAX EC to be fully field configurable, partially restricted or com- pletely restricted by way of user ID and access code.

Explosion-Proof or Intrinsically Safe

The GASMAX EC is CSA certified for use in Div 1 & Div 2 hazardous areas and can be installed as Explosion Proof (with stainless steel sensor head) or Intrinsi- cally Safe (with aluminum sensor head) using appropriate wiring techniques and an Intrinsically Safe barrier. See notes on IS installation on back. An ATEX certi- fied version for XP installations is also available.


  • Certified for Explosion Proof and Intrinsically Safe Installations
  • Non-polarized loop powered inter- face eliminates wiring errors
  • Graphic display shows values, units, trend graph, alarm levels
  • Three flashing Alarm LEDs with Programmable Alarm Levels
  • Real time clock tags alarm and calibration events
  • Supports both local and remote sensors for easy installation
  • Non-intrusive, prompted calibra- tion with programmable cal gas
  • Power-up and post-calibration delays eliminate false alarms
  • 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
  • For combustible applications, see the GASMAX II gas monitor

Note: Sensor Heads 3, 4 and 8 require INTRINSICALLY SAFE (IS) installations in hazardous locations. IS installations require an IS barrier (#10-0263 MTL 7787P+) or equivalent that must be mounted in an area designated as Non-hazardous.
