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.
