Overview
ZD-2A Potentiometric titrator is an analytical instrument suitable for a variety of Potentiometric titration, poten-tiometry, and is widely used in teaching, scientific research, environmental protection testing and Petrochemicals. The instrument integrates the host and Magnetic Stirrer, and uses a solenoid valve to control the droplet, which is intuitive and convenient to operate.
Features
1. Equipped with 7-inch color high-resolution capacitive Touchscreen, complete parameter display, adjustable screen luminance.
2. With automatic calibration, automatic temperature compensation, data storage, USB output, clock display, wireless printing, cloud interconnection and self-diagnosis and other intelligent functions, optional Bluetooth module to support wireless printing.
3. Built-in large-capacity storage, can store 2000 sets of measurement data, data can be transferred through U disk, and can be opened and edited by general office software EXCEL.
4. Support potential Titrimetric method for capacity analysis.
5. Control titration of pH value or potential can be performed, and the titration end point can be controlled according to the set potential (pH).
6. It can adjust the pre-controlled potential (pH), set the titration end point delay function, and control the titration interval.
7. It has three titration modes: manual, automatic, and controlled (constant pH/potential).
8. It can be used to determine the pH value of the sampling aqueous solution and the potential value of the measurement Electrode.
Principle
The instrument determines the titration end point by measuring the change of the potential or pH value of Electrode during the titration process. It uses a solenoid valve to precisely control the addition of the titrant, and completes the titration process in manual, automatic or constant pH/potential control mode according to the set end point potential (pH) value to achieve capacity analysis.
Applications
Teaching, research institutions, environmental testing, Petrochemicals
Standards
Instrument level: 0.5 level
Steps
1. Instrument preparation and startup.
2. According to the analysis requirements, choose manual, automatic or controlled (constant pH/potential) titration mode.
3. Set titration parameters, such as end point potential (pH) value, pre-control point, titration delay, etc.
4. Install Electrode and Titration Device and start titration.
5. After the titration reaches the end point, the instrument automatically stops, records, and stores the data.
6. You can export data through a U disk or connect a printer to output results.
Notice
• Before use, make sure that the power supply is AC voltage (220 +/- 22) V, Frequency (50 +/- 0.5) Hz.
• The instrument should be used under the conditions of Ambient Temperature 5~ 40 ℃ and Humidity ≤ 85%.
• Please pay attention to the maintenance and calibrating of Electrode during operation to ensure Measurement accuracy.
• Data storage and transfer, please follow the specifications to avoid data loss.
• The instrument has a self-diagnostic function. In case of abnormality, please refer to the prompt information or contact a professional.
