GDS GASMAX II 3-Wire Gas Detector with backlit LCD display and local stainless steel sensor head configured for Catalytic Bead sensor for Combustibles LEL (specify gas) with range 0-100% LEL (Lower Explosive Limit), 4-20 mA output transmitter with optional Alarm Relay Board (3x 5A SPDT) and RS-485 Modbus RTU. Available calibrated to Methane (Natural Gas), Ethane, Ethylene, Hydrogen, Butane, Pentane, IPA, Methanol, MEK, Propane, Propylene, Pentane and many others. CSA Certified for Class I, Div 1.

Inquiry

The GASMAX II gas monitor delivers the latest in toxic & combustible gas detection technology, reliability and ease of use.

Widest Variety of Available Sensors

Built-in dual channel electronics allow the GASMAX II to support any GDS Corp sensor or any combination of one toxic and one combustible (bridge-type) 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 II constantly tracks sensor performance and calculates an estimate of sensor life remaining.

Advanced User Interface

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.

Flexible Output Options

In addition to standard dual 4-20mA current loop outputs, an optional dual isolated 4-20mA output board or an RS-485 two-wire MODBUS® interface with three 5A SPDT relays are available to communicate with controllers or drive local alarm indicators. When used with the C1 Protector controller’s MODBUS master port, multiple GASMAX II monitors can be daisy-chained up to 500m to minimize wiring.

Reliable

Available in both single and dual channel models, the GASMAX II is CSA and ATEX certified for use in Class I, Div 1 explosion proof installations. For low temperature applications, an Arctic Monitor option add thermostatically controlled heaters to enable operation as low as –55°C ambient.

FEATURES

  • CSA Certified for Class I, Div 1 explosion-proof installations
  • Monitor both toxic sensors and LEL with one detector
  • 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
  • Backlit display for better visibility in low light conditions
  • Options for 3x 5A alarm contacts, isolated 4-20mA and MODBUS®
  • 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
