GX-2012 4 Sensor Multi-Gas Confined Space Gas Detector w/ Li-Ion Battery Pack Kit 72-0290-22-C-51

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. The GX-2012’s large LCD display shows all gas readings; battery level; current time; and will automatically backlight in alarm conditions.

FEATURES:

• Monitors ppm LEL; % volume methane; O2; CO and H2S.
• 0 to 100% volume methane option.
• Auto-ranging display of % LEL and % volume.
• 3 Operating modes: Normal; leak check; & bar hole.
• PPM leak detector.
• Adjustable display ranges.
• Visual / audible pulses change with gas concentration.
• CO display in leak check mode.
• Bar hole test mode for underground leak checks.
• Internal sample drawing pump with up to 50′.
• Vibration; visual; and audible alarms.
• Automatic backlight during alarms
• Lithium ion or alkaline battery packs (interchangeable).
• Intrinsically safe; ATEX/IECEx/CE or CSA/CE (Optional).
