Teledyne GMI GS700 Hydrogen Gas Detector
The GS700 is an all-in-one detection solution for Natural Gas and Hydrogen.
The Teledyne GMI GS700 – Hydrogen enables you to simplify gas detection with an all-in-one solution for Natural Gas and Hydrogen. Whether it’s natural gas, 100% hydrogen or hydrogen blends, this highly adaptable device guarantees exceptional flexibility and performance. The GS700 is ideal for outdoor/indoor leak detection, purging, barholing, confined space entry, and Pipeline Gas Test (PGT).
Ensuring compliance
Intelligent data-logging functionality together with optional GPS mapping simplifies data gathering. The 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 you 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.
