IRNET-P 20mm is N.E.T. IR sensor for whoever is looking for strong and dependable detection performances both at low and high volume in a standard 4-series size. 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.

IRNEx-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. Learn more about ATEX and IECEx standards in our Certifications section. IRNEx-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.

N.E.T. IREF is market’s most DEPENDABLE refrigerant gas sensor. Design your own fail-safe leak detection systems with state-of-the-art NDIR (Non Dispersive InfraRed) technology. Lower your total cost of ownership and stand out from your competition with better accuracy, selectivity and reliability. N.E.T. IREF sensors have the market’s most comprehensive range of targeted gases, allowing detection in ppm and LEL range of HFCs, HFOs and SF6 (for CO2 and Propane, please check IRNET page). You can easily expand your range, as all sensors have the same built and interface.

The revolutionary low-cost, NDIR-based sensor series for A2L refrigerant leak detection. When it comes to refrigerant leak detection, the predominant sensing technologies are undoubtedly Non-Dispersive InfraRed (NDIR) and Metal-Oxide Semiconductor (MOS). NDIR is the most performing technology, but its cost has so far prevented a widespread use in light commercial and residential applications, where MOS has remained the predominant choice.

Top quality electrochemical gas sensor range according to EN45544-2 for Harsh Environment Applications. This electrochemical gas sensor line includes solutions for Carbon Monoxide (CO), Nitric oxide (NO), Nitrogen dioxide (NO2), Hydrogen (H2), Hydrogen sulfide (H2S), Sulfur dioxide (SO2), Hydrogen chloride (HCl), Chlorine (Cl2), Ethylene (C2H4), Formaldehyde (CH2O), Hydrogen Peroxide (H2O2), Ammonia (NH3, available in 4 different ranges) and the new H2S-HT and CO-HT cells for high temperatures.

Our SHM/SHP Pellistor, or catalytic bead sensor, line is selected by N.E.T. and manufactured, on OEM basis, by the companies leading in the field. The sensor monitors the presence of a combustible gas or vapor in air (or atmospheres containing oxygen) up to the Lower Explosive Limit (LEL). SHM/SHP Pellistors consist of a matched pair of elements mounted on a single header and protected by a metal mesh filter. Both types have a standard 4-series enclosure (D20.4 mm x H100) to fit a standard gas detector. SHM housing is of stainless steel, while SHP’s is of plastic. The standard dimensions and the electrical output make our Pellistor perfectly compatible with a wide range of commercially available Gas Detection Systems and remote flammable gas detector heads.

Matched pair catalytic bead sensor for methane and combustible gas detection in LEL range. Our SMM Pellistor, or catalytic bead sensor, line is selected by N.E.T. and manufactured, on OEM basis, by the companies leading in the field. The sensor monitors the presence of a combustible gas or vapor in air (or atmospheres containing oxygen) up to the Lower Explosive Limit (LEL). SMM Pellistors consist of a matched pair of elements mounted on TO4 size headers and protected by a metal can. The matched pair is housed in standard 7-series plastic enclosure (D32 mm x H100) to fit a standard gas detector. The standard dimensions and the electrical output make our Pellistor perfectly compatible with a wide range of commercially available Gas Detection Systems and remote flammable gas detector heads.
