Confined Space Monitor GX-2009

The Confined Space Monitor GX-2009 is the world’s smallest as well as lightest personal 4-gas monitor. Weighing only 130 grams, it fits in the palm of your hand. The GX-2009 represents the latest evolution of gas detection technology. The GX-2009 simultaneously monitors and displays combustibles Oxygen (O2), Carbon Monoxide (CO2) as well as Hydrogen Sulphide (H2S). It is a compact 70(H) x 75(L) x 25(D)mm (approx.) design.

Rugged, Reliable and Robust :

Advancements include dual audible alarm ports and alarm LED’s on 3 sides of the instrument.
