GX-2012
COMPONENT DESIGNATIONS
Built around high-quality micro-sensor technology, the GX-2012 is Riken’s smallest personal 5 sensor gas monitor with a built in simple pump. Weighing only 360g, two operating modes: Normal (for confined spaces) and bar hole. The GX-2012 can monitor the standard confined space gases (LEL combustibles, oxygen content, carbon monoxide, and hydrogen sulfide), and it can also mesure 100% volume methane and dynamically display either % LEL, or % volume with its auto-ranging. The GX-2012 can be used for gas line purge testing as well as standard safety testing.
