rbr ecom-J2KN analyser

The rbr ecom-J2KN analyser utilises electrochemical sensors to measure exhaust emissions, most commonly O₂, CO, NO, NO₂ and SO₂ gases and has an available NDIR bench for measuring CO₂, high CO and CH₄.

The robust filtering system, along with the Peltier gas cooler and 9 V high ­flow pump, ensures a clean sample and high flow rate, which is necessary for accuracy and repeatability. The sensors are monitored, which compensates for temperature changes in harsh testing environments, and the CO sensor has a dedicated fresh air pump that is activated if a maximum concentration limit is exceeded — usually 4000 ppm.

Applications include emission testing on stationary engines, generators, compressors, boilers, burners, turbines, heating equipment, pumps, diesel engines, mining equipment (to control DPM), construction equipment, laboratory combustion equipment, alternative fuels research and others. The analyser is also used for fuel efficiency testing, combustion tuning, maintenance checks and emissions compliance reporting. The types of fuel burnt that can be tested include natural gas, oil, diesel, coal, wood, biomass, butane, propane, biodiesel and other alternative fuels. Gasoline emissions may be tested, but this requires the NDIR bench (for CO).
