Version (Isobutane Calibration) by RKI Instruments
|
|
|
|
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 O2 respectively with automatic ranging. The RX-415 has
explosion proof and intrinsically safe construction so that it can be used
|
|
safely in
any environment.

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
|
|
|
|
Applications
|
|
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)
