Utilising the latest infrared gas detection technology in a robust and reliable design, the GMI Gasurveyor 700 (GS700) is a highly configurable instrument with leading performance and a user-friendly interface which makes it the perfect choice for all gas utility applications. The large display simplifies operation and allows the user to access multiple functions.
The Gasurveyor 500 can contain up to six gas ranges with the following ranges being possible:
FEATURES
LEL & Volume Gas (infrared).
Optional sensors including: PPM, O2, CO, H2S.
Barhole mode - configurable.
Soft-key operation.
Communication: IrDA & optional Bluetooth.
360° Alarms.
Lightweight and rugged.
Ingress protection - IP55.
Alkaline or rechargeable battery options.
Ranges of Operation.
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.
Pipeline Gas Test (PGT)
Avoid unnecessary excavations with this invalu-able feature. Instantaneous confirmation that the gas is not from your pipeline (e.g. landfill or swamp gas).
