characteristics of instrument
pxs-ca calcium ion concentrator is produced by using microcontroller technology, which makes operation simple and convenient, and digital display intuitive and correct.
instrument has manual temperature compensation and automatic temperature compensation functions (when the temperature electrode is connected, the instrument enters automatic temperature compensation and displays the current temperature; when the temperature electrode is not connected, the instrument enters the manual temperature compensation, and the instrument displays the manual temperature setting value. the temperature electrode belongs to the selective key. if the user needs it, it should be presented when ordering.
instrument has a calcium ion concentration value [ca] display in addition to pf value display.
instruments are beautiful and lightweight.
