Advance combustion analyser


With wireless remote control, the J2KNpro adds extra convenience and flexibility to a system that is already portable! The remote display shows all values at a glance with zoom display and plug-in memory up to 2 GB.

The remote feature allows for complete operation of the analyser from the remote and makes the J2KNpro an ideal emission analyser on large combustion systems when combustion controls are located away from the measurement port.

The J2KNpro can be fitted with up to 6 gas sensors to measure O2, CO, NO, NO2, SO2, and combustibles, along with gas temperature, ambient temperature, sensor temperature, stack draft & pressure, and internal flow. Calculations include CO2, efficiency, excess air, oxygen correction, and mass emission rates.

Do your NOx levels exceed 500ppm? No? Then ask about the J2KNpro Low NOx version.
