product key technologies

This Desktop pH Meter is an intelligent pH meter centered on a microprocessor with high-precision measurement capability, specially designed for the accurate determination of solution acidity (pH value) and electrode potential (mV value) in the laboratory. When used with an ORP electrode, it can reliably measure the oxidation-reduction potential of a solution, namely the ORP value that reflects the oxidizing or reducing capacity of the system. When matched with an ion selective electrode, it can accurately detect the potential value generated by the corresponding ion selective electrode, providing basic data for ion concentration analysis.
The instrument features stable performance, sensitive response, a concise operation interface and a convenient calibration process, fully meeting the strict measurement requirements of electrochemical parameters for daily quality inspection and scientific research experiments.
With reliable performance and wide applicability, it is widely used in electrochemical analysis across light industry manufacturing, chemical production, pharmaceutical industry, food inspection, health and epidemic prevention, environmental monitoring, as well as universities and research institutes. It is one of the indispensable basic analytical tools in laboratories.
