NET PRESENTS THE MAK SENSOR AT HYDROGEN TECHNOLOGY EXPO 2025
🔹 The appointment with the future of Hydrogen: October 21–23, Hamburg
📅 October 21–23, 2025
📌 Hamburg Messe, Hamburg (Germany)
📍 NET: 6J30
From October 21st to 23rd, 2025, NET will be exhibiting at Hydrogen Technology Expo Europe at Hamburg Messe (Germany).
The event allows all the main players in this industry to showcase their technologies, which are used to facilitate the use Hydrogen in mainstream applications with the goal of securing a cleaner, more sustainable future.
The Hydrogen economy is growing rapidly across the world: it is establishing itself a key contributor to the green transition and is destined to become one of the key elements of decarbonization.
In terms of sustainability, it constitutes a valid alternative to fossil fuels, and many countries have started to heavily invest on its enormous potential, especially in Northern Europe.
However, the widespread use of Hydrogen brings new safety-related challenges, due to:
- High flammability
- Wide explosivity range
- Completely colourless, odourless, and tasteless
For these reasons, its detection needs to be fast, precise, and reliable.
The most common sensor technologies used to sense Hydrogen have significant operational limits:
- Electrochemical cells only work in the presence of Oxygen and contain an electrolyte which drains over time;
- Pellistors also only work in the presence of Oxygen and respond indiscriminately to any flammable mixture, meaning they are not selective. Furthermore, they can be poisoned by Silicones, Silanes etc.
Furthermore, as the operating principle of both types involves a chemical reaction, they require regular maintenance and replacement to ensure reliability.
🔹 THE NEW NET MAK SENSOR AND HYDROGEN ECONOMY
In this scenario, thermal conductivity emerges as an effective alternative.
NET has developed the new MAK series, i.e. MEMS Analogue Katharometer.
MAK is a thermal conductivity sensor, or KATHAROMETER, which measures the concentration of gases whose thermal conductivity differs significantly from that of the reference gas, usually air, in a range from 0 to 100% by volume.
🔹 This device measures the variation in the air’s ability to conduct heat: a parameter that changes significantly in the presence of hydrogen, the gas with the highest thermal conductivity among all known gases.
🔹 MAK thermal sensors cover the entire detection spectrum, operating effectively from ppm levels up to 100% by volume, thanks to their ability to function without oxygen.
🔹 Thermal conductivity sensors offer superior long-term stability and a longer operational lifetime compared to sensors based on chemical reactions, which gradually decay over time.
🔹 It is designed to operate over a wide temperature range, from -40 °C to +60 °C, with automatic compensation of environmental conditions (temperature, humidity, and pressure) allowing its use in various applications.
🔹 Superior resistance to mechanical shocks compared to catalytic sensors or traditional thermal conductivity sensors, another advantage of the MEMS technology with integrated membrane adopted by NET.
🔹 It is immune to poisoning, as the common poisons/inhibitors cannot stick to the active part of the sensor.
🔹 Another key factor is the fast sensor response (< 1.4 s), which is only limited by the time required for variations in the MEMS element’s resistance.
Hydrogen is at the forefront of clean energy innovation. Fully harnessing its potential means tackling major challenges in terms of production, storage, infrastructure, and more.
🔹 Hydrogen detection is required in many applications, including:
- Electrolyser plants (hydrogen production, separation from water)
- H₂ storage tanks/containers
- Hydrogen test centres
- Hydrogen vehicle depots
- Battery rooms
- Hydrogen pipelines/networks
🔹 NET will be showcasing the new MAK sensor at Hydrogen Technology Expo Europe, from October 21 to 23, 2025, at Hamburg Messe.
It will be a perfect opportunity to experience the product quality firsthand, engage in discussion, and explore specific design needs together.
