  • 💪 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 Nitrogen Oxides (NOx) exhaust and emission measurements. It is very good for diesel combustion exhaust gas. It features two high-precision electrochemical sensors. The first sensor is dedicated to Nitric Oxide (NO) measurements, offering a 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 has advanced features such as a 32-bit microprocessor, color screen, real-time graphing, and data logging functions. The massive display 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, USB charging cable, USB charger, USA NIST traceable calibration certificate, and simple English user manual.
