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.
