As the HVACR industry converges on the Las Vegas Convention Center for the 2026 AHR Expo, N.E.T. is pleased to announce our participation. 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 manufactured...
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):...
MOS (Metal-Oxide-Semiconductor) sensors have been the main go-to solution for detecting flammable Gas and refrigerant leaks for decades. Despite their affordability, MOS sensors come with significant trade-offs: frequent recalibration (every 6 months or less), short lifespan (2–4 years), and susceptibility to false alarms and environmental changes. IREF PRO by N.E.T. paved the way for the next generation of NDIR refrigerant Gas Sensors,...
Exciting product news for our users based or operating in the US and Canada: the NETC3 and NETC2 Heads have just received the certification in accordance to North American standard series UL 60079 (UL 60079-0 and UL 60079-1), and CSA C22.2 60079 (CSA 60079-0 and CSA 60079-1), specifying general requirements for construction, testing and performance applying to equipment for the...
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”...
The NT-CO-PL200 is a new, high sensitivity Premium Line electrochemical gas sensor with 3 electrodes for the detection of Carbon Monoxide in demanding gas detection applications. Exhibiting high performance with excellent stability and output signal, this compact sensor (20.4 mm diameter) is suitable both for portable and fixed gas detection instruments where the ability of accurately detecting low levels of...
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...
CATALYTIC BEAD SENSOR RELATIVE RESPONSES TO VARIOUS GASES Our Pellistor, or catalytic bead sensor, is employed to monitor the presence of a combustible gas or vapor in air (or atmospheres containing oxygen) up to the Lower Explosive Limit (LEL). 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...
