With the GX-2012, you have multiple tools in one instrument. Having 3 operating modes, the GX-2012 can be used for confined
space, safety monitoring in it’s Normal Operating mode; for leak investigation in Leak Check mode; and for underground leak
checking in Bar Hole mode. When equipped with an optional TC sensor, the GX-2012 can measure 100% volume methane
and dynamically auto range from % LEL to % volume. This is ideal for line purge testing.
Built around high-quality micro-sensor technology, the GX-2012 is RKI’s smallest personal 1-5 sensor gas monitor with a built
in sample pump. Weighing only 12.3 ounces, the GX-2012 can monitor the standard confined space gases (LEL combustibles,
Oxygen content, Carbon Monoxide, and Hydrogen Sulfide).
The GX-2012’s large LCD display shows all gas readings, battery level, current time, and will automatically backlight in alarm
conditions. Standard alarm types include vibration, visual, and audible alarms, which can be set to latching or non-latching.
Controlled by a microprocessor, the GX-2012 continuously checks itself for sensor connections, low battery, circuit trouble, low
flow, and calibration errors. The GX-2012 can interchangeably operate on either a Li-ion battery pack or an alkaline battery
pack. The batteries are simple to replace requiring no tools to access the removable battery compartment or pack.
Calibration and bump test 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-2012 is also compatible with the economical SDM-2012 single channel
calibration station.
