Riken Keiki Model RX-8500 | CO Gas Monitor

Newly designed for measuring multiple gases in inert or air atmospheres. It is a newly improved model of RX-51 Series (RX-515).

RX-8500 is designed specifically for Liquid Natural Gas (LNG) carriers.

It is used to measure gas concentrations in tanks or piping during inerting / purging and tank maintenance work.

Model 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.

It also has a strong internal pump that samples at 750ml per minute.  Equipment has a clear and intuitive digital display.
