RKI GX-2012

Confined Space Monitor

The GX-2012 is a compact confined space monitor capable of being outfitted with a 5th sensor for measuring % volume Methane in addtion to % LEL. Other advanced features include on demand datalogging, a large LCD display, and multiple ease of use features.

RKI's GX-2012 is a compact confined space monitor capable of measuring up to 4 gases simultaneously. With the addition of a 5th sensor, Methane readings can dynamically switch between % LEL and % volume. Designed for versatility, the GX-2012 features two operating modes for either standard confined space monitoring or bar hole mode, a strong internal pump capable of drawing up to 50', and advanced datalogging.

The GX-2012 is the suggested replacement for the GX-2003.

Two power options are available, standard alkaline or a Li-Ion rechargeable battery. Runtimes of up to 15 hours can be achieved with standard alkalines, and up to 10 hours with the rechargeable battery. A convienient pump pause feature allows the user to pause the pump without shutting down the instrument to conservere battery life. Li-Ion models come with a dual charger for use with a standard AC outlet or in a vehicle.

Both traditional datalogging and the new snap datalogging feature come standard. Snap datalogging allows the user to record data at a specific time on demand, traditional datalogging runs continuously. Every GX-2009 comes standard with enough memory to store 600 readings and alarm trends.

The large backlit LCD display is viewable under any conditions and the controls are easy to operate with gloves. The GX-2012 comes with a 2 year warranty and features an extremely rugged design resistant to impacts, dust, and water while weighing only 12.3 ounces.

Calibration Station Now Available

The new GX-2012 allows easy calibration, bump testing, and charging. Although the calibration station can be connected to a PC, it is perfectly capable as a stand alone unit and includes a flash drive for storing calibration, bump test, and alarm trend data for later review or archiving. Up to 10 charging stations can be linked together for simultaneously managing an entire fleet of GX-2012 detectors.
