Teledyne GMI GS700 Hydrogen Gas Detector

Overview

The GS700 provides an all-in-one gas detection solution for Natural Gas and Hydrogen applications. Whether detecting natural gas, 100% hydrogen, or hydrogen blends, this highly adaptable device delivers exceptional flexibility and performance.

It is ideal for outdoor and indoor leak detection, purging, barholing, confined space entry, and Pipeline Gas Testing (PGT), making it a versatile solution for gas utility professionals.

Ensuring Compliance

The Instrument Management System enhances fleet management by providing access to field usage reports, calibration history, investigation mapping, and customised reporting tools. This enables organisations to demonstrate compliance efficiently and effectively.

Natural Gas Discrimination

The GS700 quickly identifies whether detected gas originates from pipeline gas or naturally occurring biogas. This capability helps save valuable time while reducing detection-related costs.
