Ammonium analyzer
TresCon® OA 110
WTW
* Automatic calibration
* Short response time
* Continuous ammonium value monitoring in sewage plant effluent
* Analysis of the ammoniumnitrogen pollution in surface waters
* Monitoring water treatment plants
The continuous determination of ammonium in the OA 110 module is carried out according to the potentiometric measuring principle with a gas-sensitive NH3 electrode. Sodium hydroxide is added to the thermostatted sample to convert the ammonium dissolved in the medium into undissociated ammonia gas. The gaseous ammonia alters the pH registered by the measuring electrode; the alteration is a direct measure of the ammonium concentration in the sample.
