GX-8000: Portable Marine Multi Gas Monitor for combustible gas, O2, H2S, and CO


GX-8000 Portable Multi Gas Monitor

The Riken Keiki model GX-8000 sets a new industry standard for rugged, reliable, portable gas detection. It's tough, water proof design utilises features based on over 72 years of gas detection design experience, to assure reliability when protecting people and property from all kinds of harsh gas detection applications.

The GX-8000 is the latest sample drawing gas detector from Riken Keiki and consolidates several of the older classic models, such as the GX-111GX-111, NP-237HNP-237H, GX-7GX-7, GX-85NGX-85N, OX-62BOX-62B, OX-1OX-1, OX-415OX-415, OX-226OX-226, GP-226GP-226, etc... into one unified and improved specification. It's versatile design makes it simple to configure for 1-5 gases and the sensor compartment makes servicing sensors and filters quick and simple. Designed to international standards, CE marked and certified to ATEX / IECEx / MED (Wheelmark) approval, means it is perfectly suited to challenging industrial and marine applications.

The compact, light weight design makes it comfortable to carry using the neck / shoulder strap, and the optional waist strap allows for hands free use. The unit is easy to operate single-handedly and the powerful built-in pump has a fast 750ml / minute suction rate. A 30m length hose takes only (approx.) 30 seconds to sample a potentially hazardous or toxic gas.
