S470 Multi-probe for Ammonium and/or Nitrate
Process ISE Probe to Measure Ammonium, Potassium, Nitrate, Chlorides and Temperature
S470 is a complete family of Ion selective electrodes (ISE) probes suitable for monitoring the performance of the ammonium ion (as NH4+ or NH4–N) and nitrate ion (as NO3– or NO3–N) in a liquid matrix.
Particular attention has been paid to identify a set of sensors that are stable and also sensitive. For improved accuracy the probe includes a reference electrode with a particularly high performance and a high capacity of compensation of the pollutants.
The sensors provide accurate readings of the above analytes in the following applications:– surface waters
– wastewater
– zootechnical and industrial process water.
The S470 family consists of 3 elements:
S470/NH4+ Sensor for ammonium ion (0÷100ppm) with compensation of the potassium ion (0÷1000ppm)
S470/NO3– Sensor for nitrate ion (0÷100ppm) with compensation of the chloride ion (0÷5000ppm)
S470 Combined Sensor for ammonium (0÷100ppm) and nitrate (0÷100ppm) ions with compensation of the potassium (0÷1000ppm) and chloride (0÷5000ppm) ions
