France-based technology developed Teledyne has announced the enhanced version of its Gasurveyor 700 (GS700) gas detector, which combines hydrogen and natural gas detection into one device.
The portable GS700-Hydrogen device aims to simplify gas detection across applications such as outdoor and indoor leak detection, purging, barholing and pipeline gas testing.
According to Teledyne, development of its ATEX-certified instrument was supported by field trials aligned with the hydrogen transition efforts of prominent UK utility companies SGN and Northern Gas Networks.
Set to begin operations next year, SGN’s H100 Fife project will establish the world’s first green hydrogen gas network in Levenmouth, Fife in Scotland.
This will enable customers to choose between using natural gas or hydrogen.
Having worked together to develop the GS700-Hydrogen, SGN and Teledyne intend to support the ability to detect and locate hydrogen leaks.
“This collaborative process ensured the instrument’s suitability for emergency response and engineering teams, enabling them to precisely detect and locate both hydrogen and natural gas leaks. The collaboration resulted in refining the instrument’s operation and validating its technology,” said Teledyne in a statement.
A project undertaken between Teledyne GMI and Northern Gas Networks (NGN) was launched earlier this year as part of the UK’s ‘H21’ hydrogen homes project.
A trial undertaken by NGN aimed to ensure safety within their H21 networks and measure hydrogen during activities like purging and pipeline commissioning.

This led to the inclusion of several new display options and the ability for users to view LEL, PPM, and volume gas readings, in addition to the total flammable reading or the individual LEL readings.
Funded by Ofgem and led by NGN in partnership with several other UK gas and utilities companies, the H21 programme aims to play a key role in decarbonising the UK by 2050.
Its first project examined the gas network in Leeds and produced the Leeds City Gate feasibility study. The report concluded it was technically possible and economically viable to decarbonise the UK’s gas distribution networks by converting them from natural gas to 100% hydrogen.
