  • 💪 STRONG: Robust design with ABS and anti-slip grip rubber. Comes with a back magnet for easy mounting on the vehicle panel to enable hands-free operation.
  • 🕵️ TRUSTWORTHY: ** 1-year limited warranty ** Arrives with NIST USA calibration certificate ** Product tested and calibrated in the USA ** 


The NOx Gas Analyzer is an advanced instrumentation designed for accurate exhaust and emission measurements of Nitrogen Oxides (NOx). It features two high-precision electrochemical sensors. The first sensor is dedicated to Nitric Oxide (NO) measurements, offering a wide range of 0 - 5000 ppm with a fine resolution of 1 ppm, ensuring detailed and accurate readings even at very low concentrations. The second sensor is specifically for Nitrogen Dioxide (NO2), with a measurement range of 0 - 1000 ppm and the same 1 ppm resolution. NOx concentration is calculated by NO (ppm) + NO2 (ppm) = NOx (ppm). This analyzer is ideal for environmental monitoring, industrial applications, and automotive applications offering a dependable measurement platform. The unit is packed with advanced features such as a 32-bit microprocessor, color screen, real-time graphing, and data logging functions. The display is massive and shows the NO, NO2, and NOx in ppm concentration. We also offer the CO high-range analyzer for combustion engines and our premium 5-gas analyzer for exhaust emissions. For combustion analysis of natural gas-burning appliances, you will need our Professional Combustion Analyzer.

Included: Robust, waterproof ABS hard case, model 600 analyzer with a high range NO and NO2 sensors, niobium magnet for easy mounting, 6-inch stainless steel with alligator probe, hose assembly with 3 feet of high temp silicone tubing, water trap, particle filter, NOx filter, USB charging cable, USB charger, USA NIST traceable calibration certificate, and simple English user manual.
