GX-2012 / GT

Built around high-quality micro-sensor technology, the GX-2012 is Riken's smallest personal 5 sensor monitor with a built in sample pump. Weighing only 360g, it has many features which sets the GX-2012GT apart from the competition. For example, it can monitor the standard gas safety hazards for gas / pipeline operations, (LEL Combustibles, Oxygen Content, and Carbon Monoxide) and it also has a high-sensitivity ppm CH₄ leak tracker mode which reads down to 10ppm. It can also measure 100% Volume 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.
