The EDT direction Ammonia combination ISE is a traditional pH glass sensor with a refillable membrane cap.
This electrode does not have the solid state advantage of the Ammonium ISE 3051 but is able to detect dissolved Ammonia down to around 50ppb. For successful operation NaOH ISAB should be added to the samples and standards to ensure all the Ammonium is converted to NH3.
In principle the Ammonia penetrates the membrane and causes a change in the pH of the internal solution locally at the interface. This pH change is directly proportional to NH3 concentration. The 8302/S8 comes with an S8 connector suitable for connecting to all meters and controllers.
For direct concentration reading and absolute simplicity the EDT DR359TX pH/ION meter is the perfect instrument for these ISEs.
For Quick Ion analysis for under £500 use our ION Concentration Calculator (mV Meter Required).
EDT are a UK based manufacturer and produce ISEs for many prominent companies in the water testing sector. As a result our ISEs are very competitively priced and come complete with technical support provided from our vast library of applications and our in house electrochemistry technicians.
For optimum results use EDT directION standards and Ionic Strength Adjustment Buffers ( ISABs).
