Brief introduction: JP - 2 d oscillographic polarograph using ARM embedded system as the underlying support, friendly interface, and easy to understand, easy to operate. Instruments of various patterns (set 5 kinds of users and general), parameters, all controlled by the microcomputer setting, and stored by the real-time display polarographic curve in the testing process. Under the control of microcomputer, the instrument of polarographic and conventional one, the second derivative polarographic can adapt to various transmission range, and to early to current and capacitance current compensation automatically. Instrument can be obtained in the testing process of polarographic curve automatically measured wave height, potential data processing, etc. Suitable for colleges and universities teaching, scientific research institutes of scientific research, industrial and mining enterprises, geology, metallurgy, medicine and health care, environmental monitoring, food industry, such as soil testing department. Has become a kind of common laboratory equipment. Technical parameters: 1. The sensitivity of < 5 x 10-8 mol/l (Cd++, linear sweep polarography) 2. The resolution < 32 mv 3.
