Why it matters

Slash Fuel Costs, Avoid Fines, and Cut Greenhouse Gas Emissions

Eliminating even one ppm of NOâ‚“ today prevents both an air-quality fine and a greenhouse-gas penalty tomorrow. By cutting NOâ‚“ emissions, which drive smog and acid rain, and reducing Nâ‚‚O, which has a global warming potential 298 times that of COâ‚‚, you can slash fuel costs, avoid fines, and cut greenhouse gas emissions.

A product line-up Adapted to Your Needs

Design for Tomorrow's Regulations, Today.

The RedNOx sensor provides the precision and durability you need to meet stringent emissions standards, including the 2027 U.S. EPA & CARB 0.02g/hp−hr NOx limit. With a detection range of 1-20 ppm and an accuracy of ±10%, you can maintain warranty margins and ensure your products are compliant. The plug-and-play ECU interface and J1939 data flow simplify integration into your engine systems. The heater-optimized ceramic stack reaches temperature in less than 30 seconds, allowing you to meet cold-start FTP requirements. Our solid-state construction is resistant to sulfur, oil aerosols, and thermal shock, ensuring a field life of over 10,000 hours. Each sensor is factory-calibrated against NIST-traceable blends, and the data is stored in memory, simplifying ISO 9001 and regulatory reporting
