Description

RKI is proud to offer the smallest and lightest 4-gas monitor with an MSHA rating, the GX-2009 MSHA. Weighing only 4.6 ounces, it fits in the palm of your hand.

The GX-2009 MSHA simultaneously monitors and displays % volume methane, oxygen, carbon monoxide, and nitrogen dioxide. Equipped with dual audible alarm ports and alarm LED’s on 3 sides of the instrument, so that alarm conditions are obvious from multiple perspectives especially in high noise environments. Other features include a water resistant and dustproof design with IP 67 rating, an impact resistant rubber over-mold body that is RFI resistant, and a large capacity data logging system included as standard.

Other standard features are vibration alarm, auto-calibration, calibration and bump test lock out or reminder control, STEL / TWA readings, peak hold, auto backlighting at alarm on a large LCD display, and it even tells the time! All of these controls and features are operated through 2 simple glow-in-the dark, glove friendly buttons. The NiMH battery set will operate for 20 hours and will fully charge in 3 hours.
A huge capacity data logging function is a standard feature on all GX-2009 instruments. The data logging software will store up to 100 calibration records and is Windows 10, 8, 7, XP and Vista compatible. To simplify maintenance and record keeping, the GX-2009 MSHA has the SDM-2009 single calibration station available. The SDM-2009 calibration station can operate as a stand-alone system or connect to a computer along with up to 10 other SDM-2009 units.

MSHA (Mine Safety and Health Administration) certification allows the GX-2009 to be used in underground mines, tunnels and excavations under MSHA jurisdiction.
