**This instrument has been discontinued by RKI, but replacement parts and sensors may still be available. Please reach out to us if you're looking to repair your existing GX-2003 or if you'd like help finding a comparable replacement.**
Built around high-quality micro-sensor technology, the GX-2003 is RKIs smallest personal 4-in-1 gas monitor with a built in sample pump. Weighing only 11 ounces, it has many features which set the GX-2003 apart from the competition. For example, it can monitor the standard confined space gases (LEL combustibles, Oxygen content, Carbon Monoxide, and Hydrogen Sulfide), and it can also measure 100% volume Methane and dynamically display either % LEL, or % volume with its auto-ranging ability.
Key Features
- Three operating modes: Normal, Bar Hole, and Leak Check
- Monitors LEL, and % volume methane, O2, CO and H2S
- Barhole mode tests for peak methane and oxygen levels
- Leak detect mode offers high sensitivity tests for ppm level natural gas leaks
- 0 to 100% volume Methane option
- Auto-ranging display of % volume and % LEL
- Internal sample drawing pump with up to 40' range
- Vibration, visual, and audible alarms
- Automatic backlight during alarms
- Calibration reminder with lock out option
- Ni-MH or alkaline power source (interchangeable)
- Quick charge (complete charge in 90 minutes)
