Workplace safety is a top priority at RKI Industries. With a reputation as being a world leader in gas detection and sensor technology, the company invests heavily in their research and design team to develop the industry's leading workplace safety products. The GX-2009 Model Personal Four Gas Monitor utilizes advanced technology and efficient design. It is the world's smallest and lightest gas monitor.

The GX-2009 Model Personal Four Gas Monitor

The GX-2009 Model Personal Four Gas Monitor is an obvious choice for many particularly hazardous applications. From personal monitoring in confined spaces to its use in fire services and construction, the portable monitor has been rated intrinsically safe. Its noticeable alarm functions and simultaneous detection of four separate gases help to ensure the safety of workers in potentially dangerous situations. The state of the art monitor can detect LEL, O2, H2S, and CO simultaneously and display the results on the large LCD display screen.

Each of the miniature sensors are manufactured with the high quality control standards of RKI Instruments. The compact sensors utilize catalytic combustion, electrochemical, and galvanic sensor technology.

Alarm System

The unit features dual audible alarm ports at 95 dB, and three bright LED lights for noticeable alerts. The Personal Four Gas Monitor also utilizes an ultra strong vibration alert designed to notify users of atmospheric conditions even when the device cannot be heard. When the monitor is in alarm mode, the backlight on the LCD display is turned on. The multi-faceted alarm system is designed to be noticeable in any given situation and is sure to notify the user and those nearby.

Standard Features

The GX-2009 Model Personal Four Gas Monitor has many standard features including an incredible datalogging function. The datalogging software can store up to 100 calibration records and is compatible with many computer platforms. The log time can range from 10 to 300 hours and houses 8 alarm trends. The unit can also remind users of upcoming calibration and bump tests. With 2 glow in the dark, glove friendly buttons, users can easily operate the device on site.

The unit comes standard with an alligator clip, NiMH batteries, a charging station with VAC power supply, and a product CD with datalogging software.


The GX-2009 Model Personal Four Gas Monitor is the smallest and lightest personal gas monitor in the world. Weighing in at less than 5 ounces, the device fits easily in the palm of a hand and is easily portable. Additionally, the IP-67 water resistant and dustproof design contains an impact resistant over mold rubber body to protect the integrity of the device. The unit uses a set of 2 NiMH batteries with 20 hours of operation. Each GX-2009 Model Personal Four Gas Monitor comes standard with a 2 year warranty for materials and workmanship.
