Product Specification

ST-13 Semi-automatic potential dropper

The ST-13 semi-automatic potentiometric titrator is an instrument that uses potentiometric titration to determine the endpoint of titration by measuring potential changes during the titration process. Mainly used for chemical analysis of various components in various industries such as universities, research institutions, petrochemicals, pharmaceuticals, drug testing, metallurgy, etc

Main performance characteristics:

● Output mode: 7-inch color touch screen

● Control mode: Electromagnetic valve controls dripping, and the host is integrated with the magnetic stirrer

● Automation: It has intelligent functions such as automatic calibration, automatic temperature compensation USB output, clock display, and self diagnostic information.

● Result output: It can also be equipped with a USB drive output function to output to the PC for long-term storage

● Analysis selection: For capacity analysis using potentiometric titration in experimental applications

● Titration endpoint: pH value or potential can be controlled for titration, and the titration endpoint can be controlled according to the set potential (pH)

● Titration mode: with manual, automatic, and controlled (constant pH/potential) titration modes

● Potential value: can be used to determine the pH value of the sampled aqueous solution and measure the potential value of the electrode
