Portable gas detection
CORKE Instrument Engineering has released the GX-2003 portable gas detector. It is a 5-in-1 gas monitor with a built in sample pump.
It weighs 310g. It can monitor standard confined space gases including LEL combustibles, oxygen deficiency, carbon monoxide, and hydrogen sulfide. It can also measure 100% volume combustibles and display either % LEL, or % volume with its autoranging ability.
The large LCD display shows all gas readings, battery level, and current time. It will automatically backlight in alarm conditions. Each channel has two 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 mode, which prevents 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 Ni-Cad pack or three AA alkaline batteries. The batteries are simple to replace, requiring no tools to access the battery compartment. The Ni-Cad battery pack can receive a charge in the instrument or separately.
The GX-2003 is equipped with datalogging and a sizable memory capacity of up to 600 hours of log time. It can store 100 alarm events, 100 trouble events, and the last 20 calibrations. Up to 8 alarm trends can be stored where data is collected automatically every 5 seconds for 30 minutes before and after an alarm occurs. 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.
