NOx, SO2 and NH3 sensor, MES 1001 is developed for the maritime industry, and its harsh maritime environment. The sensor measures NOx, SO2 and NH3 gases directly in the exhaust uptake, which makes it capable of sending data updates every second. Fast and accurate measurement of emission gases is vital in meeting environmental legislation, and enables optimum use of after-treatment technologies such as Selective Catalytic Reduction (SCR).


The sensor is self-calibrating, and is consequently easy operate, and maintain. Installation is easy, and requires only pressurized air, data cable and power.

The sensor offers a variety of interfaces, including Modbus/TCP-IP, Analog Out (4-20 mA) and RS-485 for GPS data.
