SurfMoG H₂

The most effective IoT tool for continuous
hydrogen monitoring in subsurface

SurfMoG H₂ is the result of the expertise and union of a French company, 45-8 ENERGY, and a Swiss company, SOLEXPERTS.

45-8 ENERGY is specialised in subsurface exploration & production of eco-responsible gases such as helium and hydrogen.
SOLEXPERTS bases its core business on the development of world-class geotechnical, hydrogeological and monitoring instruments.

45-8 ENERGY’s knowledge of subsurface and expertise into industrial gases, coupled with SOLEXPERTS' recognised skills in terms of mechanics and electronics, led to the creation of the most effective IoT tool to monitor hydrogen, accurately and continuously over months in the subsurface:

Developed with our partner

The SurfMoG H₂ probe

An interchangeable gas analysis chamber, with an electrochemical sensor for hydrogen measurements up to 40,000 ppm (4%).

An inox probe, designed specifically to withstand the subsurface’s constraints, houses the sensor, battery and communication system.

A high-strength plastic cover, to protect antenna and assure accurate data transmission without interference from the probe's installation environment.

Probe set-up :

SurfMoG H₂ comes with a high-quality stainless-steel casing
that simplifies maintenance and makes it easy to change the probe (H₂ or CH₄/CO₂).
