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 automati-cally 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.
