INTRODUCTION
The RPB® GX4, model 08-400, tests the
quality of compressed breathing air for
Carbon Monoxide and other gases*.
Compressed Air is supplied to the unit
through the sampling hose at a constant
ow to the sensors for continuous
analysis.
KEY FEATURES:
- Multiple gasses monitored
simultaneously
- Traceability of gas levels,
temperature, alarms, air ow,
sensorchecks and more
- Internal web server for remote
monitoring, reviewing logs and
printing reports
- 3 inch LCD display and 6 buttons to
easily navigate the menus
- Exterior lights and alarms
- Auxiliary output for external alarms,
strobe lights or solenoids
- Tamper switch sealed inside of unit
- Robust protective housing
- Mounts to a Radex ltration system
- Optional wall mount bracket
- Optional protective travel case.
The monitor must be supplied with
GradeD air and must be free of oil
and water to prevent contamination
of the sensors. A micro-mist lter prior
to the Radex air ltration system is
recommended to protect the GX4 and
the operator(s). Check with your local
regulatory bodies for more information
on local requirements.
The monitor operates at 12 volts DC and
can be used with either the 110/240v AC
Adaptor (P/N: 08-430) or the 12v cable
with Battery Clips (P/N: 08-431). The unit
is designed to operate in temperature
ranges of 14° to 120F (-10 to +50C)
and Humidity levels of 5% - 99% (no
condensation).
The RPB® GX4 when used with the
Carbon Monoxide Sensor Cartridge (P/N:
08-420-01) satises the requirements of
OSHA rule 29 CFR 1910.134 for carbon
monoxide monitoring.
RPB® Safety provides maintenance
service through its service centers.
In some locations RPB® has units
available for hire while your unit is being
serviced. Contact our Customer Service
Department on 1-866-494-4599 or
