GX-2003

Built around high-quality micro-sensor technology, the GX-2003 is RKI’s smallest personal four gas monitor with a built in pump. 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.
The GX-2003’s large LCD display shows all gas readings, battery level, current time, and will automatically backlight in alarm conditions. A high sensitivity leak check mode is also included, and provides ppm level detection of gas leaks. Controlled by a microprocessor, the GX-2003 continuously checks itself for sensor connections, low battery, circuit trouble, low flow, and calibration errors.
Calibration intervals and reminders are user adjustable and calibrations can be performed automatically or individually in single calibration mode.
