The GASMAX II + GDS-IR gas monitor
combination delivers the latest in combustible & CO2 gas detection technology,
reliability and ease of use. CSA certified
for use in Class 1 Division 1 explosive environments, the GASMAX II + GDS-IR is
an ideal solution for today’s most demanding onshore and offshore applications.
Best Infrared Technology
The GDS-IR infrared combustible gas
sensor offers low cost of ownership and
a five-year MTBF rating. Designed for
harsh environments, the GDS-IR is virtually maintenance-free and immune to poisoning or etching by any known gas. The
sensor element features a self-compensating optical bench, heated optical chamber
and fault indication for all failure modes.
The optical path can be easily opened for
cleaning.
No periodic span calibrations are required.
On initial setup and after each cleaning,
a simple ‘auto zero’ procedure is used to
establish proper operating conditions.
Advanced User Interface
The GASMAX II features a highly visible backlit display and high intensity
alarm LEDs that 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 menudriven 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 + GDSIR
is CSA certified for use in Class I, Div 1
explosion proof installations.
