Portable 4-Gas Detection Solutions by Swift Marine Tech Services Pte Ltd
The Riken Keiki GX-3R is an advanced portable gas detector engineered to simultaneously monitor four critical gases with high accuracy and fast response:
- Oxygen (O₂)
- Combustible Gas (LEL)
- Carbon Monoxide (CO)
- Hydrogen Sulfide (H₂S)
Designed for dependable use in demanding marine, offshore, and industrial environments, the GX-3R combines compact handheld portability with rugged construction and highly sensitive sensor technology. It provides continuous real-time gas monitoring and immediate alarm notification, helping protect personnel from toxic exposure, oxygen deficiency, and explosive atmospheres. Its lightweight design makes it easy to carry during daily inspections, while its durable build ensures reliable performance in harsh operating conditions.
This makes the GX-3R ideal for confined space entry, engine room inspections, cargo tank monitoring, pump room safety checks, ballast tank entry, and hazardous area inspections onboard ships and offshore installations.
