Riken Keiki RX-8700 Portable Multi Gas Monitors are designed to measure multiple gases in inert or air atmospheres. Their main application is aboard Crude Oil marine tankers. They also find uses in Oil storage depots, Tank farms, Petrochemical plants and Oil refineries. They replace and improve upon the very successful RX-517.
RX-8700 users typically use them to measure gas concentrations in tanks or piping during inerting/purging and tank maintenance work. Their advanced sensor technology gives accurate gas measurement even in Nitrogen (N2) and other inert environments.
The RX-8700 has accurate measurement over the entire range of target hydrocarbons up to 100% by volume. Users benefit from dual auto-ranging technology that allows the instruments to automatically switch from a 0 – 100% LEL to a 0 – 100% volume range.
The RX-8700 has an internal pump that samples at 750ml per minute. The RX-8700 has a clear and intuitive digital display. The Instruments are explosion proof and intrinsically safe and are ATEX approved.
The RX-8700 has a compact and lightweight but very robust design. They are powered by a Lithium Ion battery pack. This gives over 15 hours of continuous operation as well as being quick to charge.
The RX-8700 has additional features that include Pilot and pump driving indicator, activating confirmation beep (1-minute intervals) and Bump Test function. Users have IrDA communications and Password Protection available. Data logger software is available as an option.
The RX-8700 is designed specifically for Crude Oil Tankers. It uses an IR sensor to measure hydrocarbon vapours over two ranges; 0 – 100% LEL and 0 – 100% volume. The Oxygen measurement range is 0-40% Volume using a Galvanic Sensor. The RX-8700 will also measure Hydrogen Sulphide (H2S) using an Electro-Chemical cell, over a 0-1000ppm range.
