Riken Keiki RX-8500 Series Portable Multi Gas Monitors are designed to measure multiple gases in inert or air atmospheres. Their main application is onboard Liquid Natural Gas (LNG). They replace and improve upon the very successful RX-515.

RX-8500 users typically use them to measure gas concentrations in tanks or piping during inerting/purging and tank maintenance work.

The RX-8500 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 has an internal pump that samples at 750ml per minute. The RX-8500 has a clear and intuitive digital display. The instruments are explosion and intrinsically safe and are ATEX approved.

The RX-8500 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 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-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.
