RKI Instruments GX-2003 Portable 4-Gas Monitor

The RKI Instruments GX-2003 is built around their high-quality micro-sensor technology, and is RKI’s smallest gas monitor with a built in sample pump and weighs only 11 ounces. It can monitor the standard confined space gases (LEL combustibles, Oxygen deficiency, Carbon Monoxide, and Hydrogen Sulfide), and dynamically displays either %LEL or %volume with its auto-ranging ability.

The GX-2003’s large LCD display shows all 4 gas readings, battery level, current time, and will automatically backlight in alarm conditions. Each channel has 2 adjustable alarm levels in addition to TWA and STEL readings for Carbon Monoxide and Hydrogen Sulfide. The TWA and STEL readings are equipped with a lunch-break (pause) mode, which prevent the average readings from being reset when the unit is turned off. Standard alarm types include vibration, visual and audible alarms that can be set to latching or non-latching. Controlled by a microprocessor, the GX-2003 continuously checks itself for sensor connections, low battery, circuit trouble, low flow, and calibration errors. The GX-2003 can operate on either a rechargeable Ni-MH pack or 3 AA alkaline batteries. The batteries are simple to replace requiring no tools to access the battery compartment. The Ni-MH battery pack can also receive a charge directly within the instrument or separately, allowing the unit to remain in service.

The GX-2003 comes standard with datalogging and a sizable memory capacity of up to 600 hours of log time. Downloading to a PC requires a cable and software, which are available separately. Calibration intervals and reminders are user adjustable and can be set to either go into alarm or to lock the user out of normal measurement mode once a calibration period has expired. Calibrations can be performed on all channels automatically or individually in single calibration mode. The GX-2003 is also compatible with the DataCal 2000 calibration station for simultaneous, hands-free service of up to 10 instruments.
