Riken Keiki Model RX-8700 | Portable Multi Gas Detector Monitors

Newly improved equipment to RX-51 Series (RX-517). The RX-8700 gas detector is designed to measure multiple gases in inert or air atmospheres.

It is designed specifically for oil tankers. Similar to the Model RX-8500, it 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 instrument to automatically switch from a 0 – 100% LEL to a 0 – 100% volume range. It has a strong internal pump that samples at 750ml per minute.

The RX-8700 has a clear and intuitive digital display, allowing for ease of readings. The Instruments are explosion-proof and intrinsically safe, with ATEX and IECEx approvals.
