The
G750 is a versatile multi-gas monitor that offers up to 6 gas detection
ranges. Available
|
|
sensor
combinations may include the detection of O2, CO, H2S,
SO2, NO2, CL2, HCN, NO,
|
|
combustibles (% Volume, %LEL), and
CO2. User selectable choice of diffusion or internal pump
|
|
sampling methods make this unit unequaled in the
market.
|
|
|
|
Configured for your application
|
|
The
sensors in the G750 may be configured to best match your industry’s needs. The
S3 (smart
|
|
sensor system) allows flexibility for user to
interchange sensors in the field. To alert the user to
|
|
increasing hazards, the unit has up to three user
adjustable alarm points.
|
|
|
|
Powerful data-logging
|
|
The
G750 data-logging option provides storage capacity for more than 30 days of
continuous
|
|
operation. Downloading is easily done through the
PC serial port that includes user name,
|
|
location, and a detailed report of exposure
levels and alarms. The user name and location
|
|
can be edited with ease for your needs.

Maintenance and security
|
|
Maintenance
will never be missed with a user determined inspection overdue alarm. Fresh
air
|
|
auto
zeroing and AutoCal® calibration make
routine maintenance effortless with no
|
|
potentiometers to adjust. To prevent
unauthorized changes to alarm values, a code must be
|
|
used to enter advanced maintenance menus for
adjustment.
