LNG Carrier Storage Vessel Gas Monitoring

Datasheet • Manual

The LNG Carrier model is a combination type portable CH4, O2, CO and CO2 gas detector with an Infrared (NDIR) type sensor, galvanic cell type sensor and Electro-chemical cell type sensor. These sensors provide accurate detection of CH4, O2, CO and CO2 levels even in N2 and other inert environemnts. The measuring ranges are 0-100%LEL / 0-100%vol for CH4, 0-25%vol for O2, 0-1000ppm for CO and 0-20.0%vol for CO2 respectively. The RX-515 has an explosion proof and Intrinsically Safe design so that it can be used safely in any environment.

Features

Dual range detection of CH4 or HC in %vol and %LEL.
Unique gas combinations include: CH4/O2/CO/CO2/HC/O2/H2S
Accurately measure CH4 or HC from inerted tanks with infrared sensor.
High range H2S 0-1,000ppm available (RX-517).
Intrinsically safe design.
Datalogging (Max 30 hours of interval trend).

Crude Oil Tanker Storage Tank Gas Monitor

Datasheet • Manual

The Crude Oil Tanker model is a combination type portable HC, O2, and H2s gas detector with an Infrared (NDIR) type sensor, galvanic cell type sensor and Electro-chemical cell type sensor. These sensors provide accurate detection of HC, O2 and H2S levels even in N2 and other inert environments. The measuring ranges of model RX-516 are 0-100%LEL / 0-10%vol for HC, 0-25% vol for O2 and 0-100.0ppm for H2S respectively. A higher range for H2S (0-1,000ppm) is available in model RX-517. A manual switch is used to change the flow to a unique path for high H2S applications to protect the other sensors. The RX-516 / RX-517 has an explosion proof and Intrinsically Safe design so that it can be used safely in any envrionment.
