Utilising the latest infrared gas detection technology, Gasurveyor 700 (GS700) is a user-friendly and highly configurable instrument that delivers leading performance in a robust and reliable design.
UK gas utilities collaborated to create a solution that detects Natural Gas and Hydrogen. The instrument detects both gases and is ideal for gas utility applications.
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 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 customised to suit user requirements, settings and languages.
Application ready
Highly configurable to our customers’ gas detection needs, providing flexibility of use without compromising performance.
Application modes include:
- Gas Leak Outdoors
- Purge
- Search
- Barhole -allows underground leaks to be located
- Confined Space
