Brief introduction of ion meter
The ion meter is an electrochemical analyzer used to measure the ion concentration in a solution. Measurement of H + also belongs to the ion meter, we generally call its PH meter or acidity meter, the general people refer to the ion meter is measured in addition to H + other than the electrochemical electrochemical instruments.
Features of NANBEI ion meter:
1. Bigger color touch screen with navigation operation;
2. Smart operation system, support functions such as methods management, electrode management, calibration management, data management, user management etc.
3. To support electrode management, up to 5pcs pH electrodes, 5 pcs ORP electrodes and 5 pcs ion selective electrodes, each can store 20 sets of calibration records;
4. It supports quick switch between various concentration units such as μg/L,mg/L,g/L,mol/L,mmol/L,PX.
5. It supports several ion modes such as H+, Ag+, Na+, K+, NH4+, Cl-, F-, NO3-, BF4-, CN-, Cu2+, Pb2+, and Ca2+ . The user can also set up specific ion mode.
6. To support Buffer group management, automatic identification of 25 kinds of buffer solutions, such as DIN and NIST. Up to six-point calibration;
7. To support firm ware upgrade and contact with PC or auto sampler;
8. To support storing 100 sets of measurement methods and 1000 sets of results;
9. To meet GLP norm;
