PX type universal Ion Meter is a DC amplifier with high input impedance and deep negative feedback. It is a secondary instrument that can be matched with various ion selective electrodes for measurement. The instrument can read the potential generated by the ion electrode in the solution, and point out the corresponding ion content. In the millivolt block, the electrode potential related to the ion activity ax can be measured, and in the px block, the logarithm px of the ion activity ax can be measured directly. The price is low and easy to operate, easy to use, very popular with laboratory workers.
The maintenance of the Ion Meter is a complex and subtle work, which requires mastering and understanding the basic characteristics and circuit principles of the Ion Meter and selective electrodes, comprehensively judges and analyzes the faults of the Ion Meter, and takes appropriate measures to find out the faults , can be more accurate, fast, and good troubleshooting, with blind dismantling and random movement, will cause adverse consequences.
