NOx, SO and NH analyzer

MES 1001

Precise and continuous measurement

MES 1001 enables precise and continuous measurement of the environmentally harmful gasses NOx, SO and NH, directly in the exhaust pipe, which ensures fast and accurate measurement.

Measurement of NOx, SO and NH

The increasing global focus on the environment and energy efficiency are the key drivers for our NOx, SO and NH sensor, MES 1001. The sensor has been developed with the purpose of enabling the maritime industry to create transparency of their emissions and turn this information into competitive advantages, through favorable total cost of ownership.

NOx, SO and NH sensor, MES 1001 is used after after-treatment technologies, such as Selective Catalytic Reduction, as a reliable emission monitoring solution for verification and optimization purposes, as well as Continuous Emission Monitoring System to document reductions required by regulation.
