RKI Instruments GX-2009 4 Gas Confined Space Monitor

It is RKI's pleasure to provide you with GX-2009. It is the smallest, lightest and the most efficient 4-gas monitor display currently present in the world.

It weighs only 4.6 ounces and is extremely compact as it can fit in the palm of your hand. The Gx-2009 has the capability of simultaneously monitoring combustible particles, oxygen, carbon monoxide and hydrogen sulfide levels present in the gas. Gx-2009 truly is a remarkable piece of technology and showcases the evolution of gas detection technology over a relatively short span of time.

It possess significant advancements over the previous models, it now includes a dual audible alarm port and an alarm LED's on 3 of the four sides of the device.

These specific advancements are to highlight alarm conditions from various other perspectives and aid the user in particularly difficult situations where in the user may encounter rather difficult situations such as a relatively high noise environment. Some other technical advancements in the GX-2009 are that it is completely water-resistant and dust proof with an IP rating of 67.

It is completely RFI resistant because of the introduction of a rubber- mold to the body . Besides these technical advancements it is still capable of performing all the other activities performed by a gas monitor and has relatively large data logging system which is installed in all standard gas monitoring devices.
