Riken Keiki RX-8700 Precision 3-Gas Portable Monitor

Product Introduction

The Riken Keiki RX-8700 Precision 3-Gas Portable Monitor is a high-accuracy handheld device engineered to deliver reliable detection of hydrocarbons (HC), hydrogen sulfide (H₂S), and oxygen (O₂). Designed for demanding industrial environments, it combines advanced sensing technology with robust features to ensure safety in critical operations such as tank inspections, gas-free procedures, and tank cleaning. With its dual-range H₂S detection, auto-ranging IR HC sensor, and long-reach sampling capabilities, it stands as a trusted tool for professionals in maritime and chemical sectors.

Features

• High-precision detection of three key gases: hydrocarbons (HC), hydrogen sulfide (H₂S), and oxygen (O₂), covering essential safety hazards in industrial settings.​
• Dual-range H₂S sensor with a high range of 0 – 1,000 ppm, enabling versatile monitoring from low to high concentrations.​
• Auto-ranging IR HC sensor that transitions seamlessly from % LEL (Lower Explosive Limit) to % Vol. (Volume), providing comprehensive hydrocarbon measurement.​
• Inert monitoring functionality to support safe operations in environments with inert gases.​
• Internal sample drawing pump with an impressive 30-meter range, allowing remote sampling from hard-to-reach areas like cargo and ballast tanks.​
• Intrinsically safe design certified by ATEX, IECEx, and MED, ensuring safe use in explosive and hazardous atmospheres.​
• IP-67 rating for dust tightness and water immersion resistance, enhancing durability in harsh working conditions.​
