1. Application of ZD-2A automatic potentiometric titrator:
The ZD-2A automatic potentiometric titrator is suitable for various potentiometric titrations and is widely used in teaching, scientific research institutions, environmental testing, petrochemicals, and other fields.
2. Characteristics of ZD-2A automatic potentiometric titrator:
A 7-inch color high-resolution (1024 * 600) capacitive touch screen with high sensitivity and complete parameter display. It uses an electromagnetic valve to control dripping, and the host is integrated with a magnetic stirrer to avoid complex instrument installation. It is easy to use, simple, and user-friendly, with adjustable screen brightness.
It has intelligent functions such as automatic calibration, automatic temperature compensation, data storage, USB output, clock display, wireless printing, cloud interconnection, and self diagnostic information.
The built-in large capacity storage can store 2000 sets of measurement data, which can be transferred through USB storage. The stored data can be opened with the general office software EXELL for easy editing by customers.
● For capacity analysis using potentiometric titration in experimental applications
● pH or potential controlled titration can be performed, and the titration endpoint can be controlled according to the set potential (pH)
● Pre controlled potential (pH) adjustment can be performed, titration endpoint delay function can be set, and titration interval duration can be controlled
● Equipped with manual, automatic, and controlled (constant pH/potential) titration modes
Can be used to determine the pH value of sampled aqueous solutions and measure the potential value of electrodes
