GX-2009 One to Four Gas Personal Monitor

The GX-2009 one to four gas personal monitor picks up where the GX-2001 left off. Among the many advancements are dual audible alarm ports and alarm LEDs on 3 sides of the instrument. This allows alarm conditions to be visible from multiple perspectives, especially in high noise environments. Other features include a water and dust proof design with IP 67 rating, an RFI and impact resistant rubber over-mould body and a large capacity data logging system.

Weighing only 130g, the GX-2009 is the smallest and lightest 4-gas monitor in the world, it fits in the palm of your hand (70mm H x 70mm W x 25mm D). The GX-2009 one to four gas personal monitor simultaneously monitors and displays combustibles, oxygen, carbon monoxide, and hydrogen sulphide.

Other standard features are vibration alarm, autocalibration, calibration lock out or reminder control, STEL / TWA readings, peak hold, auto backlighting at alarm on a large LCD display, and it even tells the time! All of these controls and features are operated through 2 simple glow-in-the dark, glove friendly buttons. The NiMH battery set will operate for 20 hours and will fully charge in 3 hours. A huge capacity data logging function is a standard feature on all GX-2009 instruments, and will store up to 8 alarm trend sessions where readings are recorded 30 minutes before and after an alarm event. The data logging has a 3,600 data point capacity with a log time range of 10 to 300 hours based on programmable interval times. The data logging software will also store up to 100 calibration records and is Windows XP, Vista and Windows 7 compatible. The GX-2009 is also functional with the data cal 2000 instrument maintenance system and the SM-2009 single calibration station.
