water analyzer / dissolved ammonia / pH / for integration

Operational Principle

The sample is fed into the stripper and sodium hydroxide solution is added to raise the pH to 14. The equilibrium of NH3 NI-144 is driven to the side of the neutral ammonia which is stripped off the sample. The stripped ammonia is trapped in the conductivity measuring cell filled with de-ionized water. The concentration of ammonia is calculated from the increase in conductivity after a preset time.
The de-ionized water is regenerated before each measurement by an ion-exchanger.

Reliability

By using only high quality components we are able to deliver a very robust instrument that has an excellent reliability. Time for maintenance is a few hours per year only. All parts are easily accessible and are replaced in a few minutes. The user himself can do all maintenance work. Down times of the instrument are minimized!
Very robust method Not only the technical construction of the AMX is very robust, but also the measuring procedure shows hardly any interference. Due to the measuring method the instrument shows almost no drift. Therefore calibration has to be done in large intervals only. Since no reagents are required which show changes over time or can be prepared wrongly a second source of errors is eliminated.
