ATEX & IECEx certified NDIR gas sensor for CO2, methane, propane and other hydrocarbons



IRNET-P 20mm is N.E.T. solution for whoever is looking for an ATEX or IECEx certified IR sensor with strong and dependable performances both at low and high volume. With a standard 4-series built, the low power version (45 mA) is perfect for a portable gas detector while the standard version fits smaller detection heads and compact detectors.
IRNET-P 20mm detects CO2 or hydrocarbon gases such as propane and methane in LEL range. The 0-100%Vol range version features N.E.T. DYNAMIC technology for the highest sensing accuracy ever seen in a compact sensor. DYNAMIC sensors also provide an optional digital output for Propane detection over 0-2.1% Vol range – the best option to detect different hydrocarbons using a cross-reference factor. DYNAMIC sensors are suited for instrument manufacturers that want to design Methane and Propane detectors in compliance with the Chinese Mine standard.
All N.E.T. IR sensors run on a microprocessor-based platform for internal signal processing, providing a linearized and temperature compensated output in digital and analogue format – the ideal solution for instrument manufacturers, even without any specialist knowledge in IR technology.
