Main functions:

The specially designed precision metering pump, three-way conversion valve and other liquid circuit parts are made of special materials, which have good corrosion resistance and can ensure continuous operation all year round. Built in precision automatic polarity reversal circuit, automatically tracks the endpoint potential, and from the start of one click titration to the end of the measurement, users do not need any further operation, which is convenient to use and overcomes human errors. It can be used as a precision pH meter in the laboratory. This instrument has functions such as automatic titration, and the volumetric titration value is directly displayed by LED digital display, which is very convenient and intuitive for both manual dripping and preset endpoint automatic titration.
