GX-2012GT
COMPONENT DESIGNATIONS
Built around high-quality micro-sensor trchnology, the GX-2012GT is Riken’s smallest personal 5 sensor monitor with a built in sample pump. Weighing only 360g, it has many features with set the GX-2012GT apart from the competition. For example, it can monitor the standard gas safety hazards for gas/pipeline operations, (LEL combustibles, oxygen ceontent, and carbon moxide), and it also has a high-sensitivity ppm CH₄ leak tracker mode which reads down to 10 ppm. It can also measure 100% molume methane and dynamically display either %LEL, or % volume with its auto-ranging ability. The GX-2012GT is excellent for gas line purge testing and detection of small gas leaks.
