In the world of Non-Dispersive Infrared (NDIR) Gas detection, the ability to see a Gas molecule depends entirely on the infrared radiation source. At N.E.T., we have engineered our sensors to surpass the limitations of conventional technology by mastering the physics of Black Body radiation. The Conventional Limit: Filament Lamps For years, the industry standard for CO2 and hydrocarbon detection has...

We will showcase our latest innovations...
NET Cyber Heads are ready-to-use enclosures that combine Gas sensors and signal-processing electronics. These units function as either integrated components for Gas detectors or as standalone field devices. Applications for Manufacturers and Integrators The Cyber Head series is engineered for OEMs and system integrators seeking to streamline product development. Utilizing these pre-certified units eliminates the need for: In-house sensor development or sourcing. Designing firmware...
In the 2026 energy landscape, gas-fueled power plants can compensate the intermittency of renewable sources; however, managing the chemical energy of natural Gas requires extreme precision. For gas detection system manufacturers, providing reliable solutions for thermal power plants is a key priority. Certified Safety: SIL2 and ATEX Compliance In the power supply industry, certifications are the primary drivers of trust. Functional Safety: All N.E.T....
In the field of industrial safety, Gas detection is often synonymous with chemical sensors. However, as industries push toward the Hydrogen economy, traditional chemical and catalytic methods reach their physical limits. The alternative is a measurement principle based on pure physics: Thermal Conductivity Gas Sensing, also known as Katharometer. Understanding the Physical Principle Thermal Conductivity is an intrinsic physical property of a Gas,...
N.E.T. is pleased to announce our participation as the HVACR industry converges on the Las Vegas Convention Center for the 2026 AHR Expo, From February 2–4, our team will be available at Booth 1851 (Central Hall). N.E.T. reinforces its focus on supplying the most complete range of Refrigerant Gas detection solutions for the HVAC+R market. Our solutions are designed and...
Hydrogen is regarded as the future of clean energy, but its use requires high safety standards. As a highly flammable, odourless gas with an extremely high dispersion rate, constant monitoring is not only an operational necessity but also a critical requirement for every infrastructure, from electrolyzers to refuelling stations. In this scenario, traditional detection technologies, such as pellistors and electrochemical cells,...
What does ATEX stand for? The term ATEX is derived from the French title of the 94/9/EC directive: Appareils destinés à être utilisés en ATmosphères EXplosibles. It encompasses two European Directives that establish minimum safety requirements for equipment and workplaces within explosive atmospheres. What are the two primary ATEX Directives? ATEX legislation is divided into two specific areas of responsibility: Directive 1999/92/EC (Workplace Directive):...
NET NDIR SENSORS WARMUP TIME: FULL OPERATION vs. FULL SPECIFICATIONS The Data Sheet and User Manual for all our NIDR sensors states that warm-up time is 60 seconds for full operation at 25 °C and at least 30 min for full specifications. We are often asked what is the difference between these two conditions. At power-up the sensor performs initial “bootstrap”...
A Pellistor, or catalytic bead sensor, monitors the presence of a combustible gas or vapor in air (or atmospheres containing oxygen) up to the Lower Flammable Limit (LFL). A Pellistor operates on the principle that when a combustible gas/air mixture is in contact with the catalyst surface, maintained at about 500°C as current is passed through it in a Platinum...
