The JP-2E type oscilloscope, launched in 2009, is a new type of oscilloscope specifically designed for users who require accurate measurement and analysis of large quantities of samples. The instrument is computer-controlled and analyzed, and can be operated with a mouse, greatly improving its lifespan and analysis functions. Data can be replicated or imported into EXCEL for statistical analysis, and curves can be distinguished and defined using multiple colors. The printer can be adapted to users' needs, greatly facilitating their convenience.

The instrument is equipped with linear sweep polarography, stripping voltammetry, cyclic voltammetry, and derivative polarography of various methods; Has high reliability, stability, reproducibility, and accuracy.
The instrument meets the needs of users to measure different substances and contents in the same sample under different testing methods, such as continuous measurement of tungsten and molybdenum; Lead and zinc are continuously measured, and the instrument also meets the measurement requirements of soil molybdenum, leaf molybdenum, tin, edible pigments, aniline, etc. The various modes (5 user-defined and universal) and parameters of the instrument are all set, controlled, and stored by the computer. During the testing process, the polarographic curve is displayed in real time and data will not be lost in case of sudden accidents.

Under the control of the computer, the conventional polarography and first and second derivative polarography of the instrument can adapt to various ranges and automatically compensate for the initial current and capacitance current. The instrument can automatically measure the wave height, potential, and other parameters of the polarographic curve obtained during the testing process, and analyze and process the data. The instrument can use three quantitative methods: standard curve method, standard comparison method, and standard addition method to process measurement data, display data related curves, equations, coefficients, and directly calculate the content of the sample. The instrument can store and print the user's polarographic curve, and can call, edit, and summarize (Office data).

JP-2E polarographic analyzer is suitable for teaching and research in colleges, research institutes, industrial and mining enterprises, geological metallurgy, medicine and health, environmental monitoring, soil testing, agricultural product testing, disease control centers and other departments.
