The OnlineNH3 is used for the continuous quantitative determination of ammonia gas (NH3) in gas mixtures.

The system is designed with an integrated dilution step for measurement of very high concentrations (100 – 20000 ppm). Also very low contents in the range of odour treshold (0.1 – 100 ppm) can be measured.

The OnlineNH3 contains a selective amperometric sensor with gas selective membranes, membrane pumps for gas transportation and sample transfer and an integrated PC for continuous recording of measurement data, trends and alarm states. The measurement values can be transmitted via digital (alarm-) and analog outputs into the control room.

Due to an integrated cleaning system the gas analysis in O2 free gases (e. g. biogas) is realized without any drift effects. Because of the stress free mode of operation, the sensor lifetime is considerable increased.

The operation principle makes the OnlineNH3 ideal as a basis for NH3 adjusted regulation of enrichment and cleaning steps.

The instrument is available in the same design for monitoring of hydrogen sulphide (H2S), sulfur dioxide (SO2) or ozone (O3).
