Built around high-quality micro-sensor technology, the GX-2003
is RKIs smallest personal 5-in-1 gas monitor with a built
in sample pump. Weighing only 310g, it has many features which
set the GX-2003 apart from the competition. For example, it
can monitor the standard confined space gases (LEL combustibles,
Oxygen content, Carbon Monoxide, and Hydrogen Sulfide), and
it can also measure 100% volume Methane and dynamically display
either % LEL, or % volume with its auto-ranging ability.
The GX-2003s large LCD display shows all gas readings, battery
level, current time, and will automatically backlight in alarm
conditions. This unit also has a special bar hole mode to
facilitate locating underground gas leaks. A high sensitivity
leak check mode is also included, and provides ppm level detection
of gas leaks. A special variable frequency alarm helps to
pinpoint the leak without looking at the instrument display.
Other standard mode alarm types include vibration, visual,
and audible alarms that can be set to latching or non-latching.
Controlled by a microprocessor, the GX-2003 continuously checks
itself for sensor connections, low battery, circuit trouble,
low flow, and calibration errors. The GX-2003 can interchangeably
operate on either a Ni-MH battery pack or 3 AA alkaline batteries.
The batteries are simple to replace requiring no tools to
access the battery compartment. The Ni-MH battery pack can
receive a charge directly within the instrument or separately,
allowing the unit to remain in service.
Calibration intervals and reminders are user adjustable and
can be set to either go into alarm or to lock the user out
of normal measurement mode once a calibration period has expired.
Calibrations can be performed automatically or individually
in single calibration mode. The GX-2003 is also compatible
with the economical SM-2003 single channel calibration station.
