GX-2012 Multi Gas Monitor

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.

As low as $845.00

Benefits:

Versatility: The GX-2012 offers multiple tools in one instrument with three operating modes: Normal Operating mode for confined space and safety monitoring, Leak Check mode for leak investigation, and Bar Hole mode for underground leak checking.

Methane Measurement: When equipped with an optional TC sensor, the GX-2012 can measure 100% volume methane and dynamically auto range from % LEL to % volume, making it ideal for line purge testing.

Compact and Lightweight: The GX-2012 is RKI's smallest personal gas monitor, weighing only 12.3 ounces, making it easy to carry and wear.

Gas Monitoring Capability: It can monitor the standard confined space gases, including LEL combustibles, Oxygen content, Carbon Monoxide, and Hydrogen Sulfide.

Comprehensive Display: The large LCD display provides clear visibility of gas readings, battery level, current time, and automatically backlights in alarm conditions.

Alarm Options: It offers standard alarm types, including vibration, visual, and audible alarms, which can be set to latching or non-latching as per user preferences.

Self-Check and Diagnostics: The GX-2012 continuously checks itself for sensor connections, low battery, circuit trouble, low flow, and calibration errors, ensuring accurate and reliable operation.

Battery Options: The GX-2012 can interchangeably operate on either a Li-ion battery pack or an alkaline battery pack, providing flexibility in power source selection.

Easy Battery Replacement: The batteries are simple to replace and do not require tools to access the removable battery compartment or pack, simplifying maintenance.
