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.
FEATURES

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

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.
