It is used for precisionly test PH of various solution and corresponding iron concentration when it is equipped with ion-selective electrode,which can also be used as potentiometric titrator that has temperature function

 Automatically calibrate,the calibration program starts through combination key,soit can avoid to the data losting for the misoperation

 3 groups of standard solution are optional,is suitable for different custom in different countries.

 The electrode state and slope displaying tell you the using condition of the electrode at any time

Automatic end point lock function, eliminate reading error.

 Can test PH,oxidation-reduction potential and ion concentration with the method of calibration curve method

 Automatic and manual temperature compensation intelligently switch             It can store the correction data for 10 years after shutdown

 with USB interface
