JK-PHM-006  Microprocessor pHmV Meter

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
