PXD-12A digital ion meter is a precision secondary instrument. Used with various ion selective electrodes. Accurately measure the battery electromotive force generated by electrodes in solution. Directly read the negative logarithm of ion activity in a solution(pX)Value. The instrument can also be used as a precision acidity meter and a high input impedance precision millivolt meter. Widely applicable to medical, environmental protection, scientific research, colleges and universities, and industrial and mining enterprises, it is an essential conventional analytical instrument for chemical analysis.

PXD-12The digital ion meter has an automatic temperature compensation function and is equipped with a dedicated temperature measuring electrode that can measure the temperature of the measured solution at any time. After inserting the temperature electrode, the instrument can automatically perform temperature compensation. The temperature adjustment potentiometer will automatically fail. If the temperature electrode is not inserted, the instrument will switch to manual temperature compensation and rely on manually adjusting the temperature potentiometer for temperature compensation.

PXD-12The digital ion meter can be equipped with various ion selective electrodes-Fluorine, chlorine, bromine, iodine, mercury, copper, lead, sodium, potassium, ammonia, nitrate, flat glasspHCone shapedpHSulfur, silver, calcium, cadmium, borate ions, etc
