NOx Analyser

The ECM NOx 5210 is a versatile NOx, Lambda and O2 analyser ideal for the development of diesel, lean burn, HCCI and gas turbine engines.

NOx, Lambda and O2 are measured using a ceramic sensor that is mounted in the exhaust of the engine. The 5210 is easy to operate and no sample lines or pumps are required, simplifying installation and giving fast response.

The NOx 5210 is remarkably compact and is suited for both dynamometer and in-vehicle applications. With six analogue outputs, CAN, USB, and RS232 communication, the NOx 5210 can be integrated into any data acquisition system and in the loop of a real-time emissions control strategy.

Two NOx Analyser options are available:

  • NOx 5210t: Suitable for engines and combustion systems that can operate rich and lean of stoichiometric. Most spark ignition engines fall into this category.
  • NOx 5210g: Suitable for engines and combustion systems that operate lean of stoichiometric (i.e. Lambdas greater than 1). Most diesel engines and gas turbine engines fall into this category.
5210 Parameter Range Accuracy
NOx Range 0 to 5000 ppm +/- 15 ppm (0 to 1000 ppm)
or +/- 20 ppm (0 to 1000 ppm)
(depending on sensor/module choice)
Lambda Range 0.4 to 25 0.008 (at Lambda =1)
AFR Range 6 to 364 +/- 0.15 AFR (at 14.6 AFR)
%O2 Range 0 to 25% +/- 0.4 (at 0 to 2% O2)
*Pressure Range 0 517 kPa +/- 5.2 kPa

* pressure compensation is an optional feature
