Riken Keiki RX-8500 Series Portable Multi Gas Monitors for Oil and LNG
The Riken Keiki RX-8500 Series Portable Multi Gas Monitors are designed for measuring multiple gases in inert or air atmospheres. Their main application is aboard Liquid Natural Gas (LNG) and 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-515/516/517 family.
RX-8500 series 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.
There are two versions of the instrument in the series.
The RX-8500 is designed specifically for Liquid Natural Gas (LNG) carriers. It has IR sensors for Methane (CH4) 0 – 100% LEL and 0 – 100% Volume( Autoranging). Carbon Dioxide (CO2) 0-20% Volume as well as an Electro-Chemical sensor for Carbon Monoxide (CO) 0-1000ppm. A Galvanic Sensor for Oxygen with a 0-40% Volume range is also included.
Auto-ranging Technology :
The RX-8500 Series 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-8500 Series has an internal pump that samples at 750ml per minute. The RX8500 has a clear and intuitive digital display. The Instruments are explosion and intrinsically safe and are ATEX as well as MED approved.
The RX-8500 Series 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-8500 series 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 also available. Data logger software is available as an option.
