Built around high quality micro-sensor technology, the GX-2012 is a very small 5-sensor gas monitor with an integrated sample pump. Weighting only 360g, two working modes: Normal (for confined spaces) and bar hole. The GX-2012 can monitor standard confined space gases (LEL combustibles, oxygen content, carbon monoxide, and hydrogen sulfide), and it can also measure 100% volume methane and dynamically display either %LEL, or %volume with self-ranging. The GX-2012 can be used for gas line purge testing as well as standard safety testing.
