The WL-15B microprocessor ionizer is an electrochemical analysis instrument that uses direct potentiometry to accurately measure the ion concentration, redox potential, and temperature of a solution. The instrument is designed with humanization based on the Nernst equation and microcomputer technology. During the measurement process, the large screen LCD display can display various status information and measurement results in real time.

Main features:
By using different ion selective electrodes, the concentration of more than ten ions can be measured. The ion concentration has three units (pX, mol/L, mg/L), which can automatically or manually determine the stable time of the ion selective electrode response. It has automatic or manual temperature compensation function, real-time display of ion name, analysis method, ion concentration, temperature, time and other status information or measurement results. It has functions such as printing, storage, data query, power-off protection and intelligent self inspection. It is equipped with RS232 communication interface and dedicated communication software. This instrument is suitable for colleges, research institutes, environmental monitoring, industrial and mining enterprises and other departments.
