Benchtop pH/Ion Meter - Touch Screen ISE and pH Meter - -2.000 to 20.000 pH - ±0.002 pH Accuracy

The Master Science Benchtop pH/Ion Meter combines a high-accuracy pH channel with ion-selective electrode measurement, mV/ORP and temperature. pH is read from -2.000 to 20.000 with ±0.002 pH accuracy, and ion concentration from 1E-9 to 9.999E9 in the unit of choice.

More than ten ion methods are built in, among them fluoride, chloride, bromide, iodide, nitrate, ammonium, potassium, sodium, calcium, copper, lead and silver, and users can define their own. A 7-inch colour touch screen manages users, calibrations, methods and data.
