Utilising the latest infrared gas detection technology in a robust and reliable design, the Gas Surveyor 700 (GS700) is a highly configurable marine gas detecting instrument. With ATEX approval, the Gas Surveyor is the complete shipping solution.

Product Description


The GMI Gasurveyor complies with international marine regulations for Gas Leak Outdoors, Purge, Search, Barhole, Confined Space and many other marine applications in vessels such as LNG / LPG Tankers, Oil Tankers, Fruit Carriers, and Refrigerated Cargo Ships.

Up to 5 gases can be simultaneously measured and displayed. The basic instrument can measure 0-100% LEL and 0-100% VOL GAS. The LEL range indicates the explosivity of the flammable gas in the sample. This is displayed as a percentage of the lower explosive limit (LEL) of the gas. Other models can measure the following gas types: Oxygen (O2), Hydrogen Sulphide (H2S) and Carbon Monoxide (CO).

Ensuring compliance
Intelligent data-logging functionality together with optional GPS mapping simplifies data gathering. Our Instrument Management System improves fleet management by providing access to field usage reports, calibration history, investigation mapping and many other bespoke reports; making it easier for our customers to demonstrate compliance.

Natural gas discrimination
Quickly determines the source of gas leaks, whether it’s pipeline gas or naturally occurring biogas; saving valuable time and reducing detection related costs.

Flexible configuration
The GS700 can be configured to meet specific application needs and can be customised to suit a range of user requirements, settings and languages.
