| Abstract: | In this paper a new type of numerical pH-meter was described. It is made of co-electrodes, highly input resistance components as well as large scale integrated circuit. Liquid-crystal display is employed for the measurement of pH values, meanwhile this pH-meter also owns a lobat (low-battery) display which may remind users of replacing the futile batteries promptly. Small size, light weight and easy reading, make it suitable for laboratories and fieldwork purposes. The technical indexes demanding for this meter during the measurement and the ways by which these indexes were given have been explained. Emphasis is to lay on the normalization principle of A/D connector and the test results obtained by the machine. |
