Ammonia e Nitrates

Combined probe ISE (selective ion electrode) – The combined probe can measure ammonia (with potassium compensation), nitrates (with chlorine compensation) and the mix of ammonia with nitrates (with potassium and chloride compensation). Each selective ion is constituted by two semi-conductor cells. The difference between the two is proportional to the ion to be measured. Measuring gamma: NH 4+  0/100 ppm; K+  0/1000 ppm; NO3–  0/100 ppm; CL–  0/5000 ppm; Temperature 0/50  ºC.
