Riken Keiki RX-8700 High Accuracy Portable Gas Monitor (HC/H2S/O2 Detector)

Product Introduction

The Riken Keiki RX-8700 is a high-precision portable gas monitor designed for simultaneous detection of hydrocarbons (HC), hydrogen sulfide (H2S), and oxygen (O2) in hazardous environments. Engineered for industrial safety, it features dual-range H2S sensing, an auto-ranging IR HC sensor, and an internal sampling pump with a 30-meter reach. With intrinsic safety certifications (ATEX/IECEx/MED) and an IP67 rating, this monitor ensures reliable operation in harsh conditions, making it ideal for maritime and confined space applications.

Product Features

Advanced Sensing Capabilities

Dual-Range H2S Detection:

Low range: 0–100 ppm for precise monitoring.

High range: 0–1,000 ppm for emergency response in high-concentration scenarios.

Auto-Ranging IR HC Sensor:

Measures hydrocarbons from % Lower Explosive Limit (LEL) to % Volume (Vol.), adapting to varying gas concentrations without manual adjustment.

O2 and Inert Gas Monitoring:

Tracks oxygen levels (0–30% VOL) and detects inert gases to prevent asphyxiation risks.

Robust Sampling & Connectivity

Internal Sample Pump:

Draws samples from up to 30 meters away, enabling remote monitoring in hard-to-reach areas.

Intrinsic Safety Certifications:

Complies with ATEX, IECEx, and MED standards for use in explosive atmospheres (Zone 0/1/2).

IP67 Protection:

Dust-tight and waterproof (up to 1 meter for 30 minutes), suitable for harsh industrial and maritime environments.

User-Friendly Operation

Intuitive Display:

Real-time gas concentration readings with visual/audible/vibrational alarms for quick threat identification.

Long Battery Life:

Extended operation for continuous monitoring during prolonged inspections.

Data Logging & Export:

Stores measurement history for post-analysis and compliance reporting.
