RX-415

LEL / O2 or CH4 / 02 for LNG, LPG, & cude oil tankers.

Features

  • Available to measure from higher concentration (vol%) to lower concentration (%LEL)
  • Explosion proof (Detector: Explosion proof, other electrical circuit and pump, intrinsically safe design)
  • Available to measure HC/O2, CH4/O2 in N2, inert gas and air with a reliable NDIR method

Description

This model has two versions and is a combination type portable HC/O2 or CH4/O2 gas detector with an Infrared (NDIR) type sensor and galvanic cell type sensor. These sensors provide accurate detection of HC/O2 (HC version) or CH4/O2 (CH4 version) levels even in N2 and other inert environments. The measuring ranges are 0-100%LEL/0-100 vol% for HC or CH4 and 0-25 vol% for )2 respectively with automatic ranging. The RX-415 has explosion proof and intrinsically safe construction so that it can be used safely in any environment.

Application

  • Measures gas concentrations in tank of LNG and LPG carriers
  • Measures gas concentrations in crude oil tankers
  • Measures gas concentration in inert gas generating system (IGS)
