Overview
The BZY-3B liquid surface/interfacial tension instrument is an economical and practical product of the CNSHP brand, and the main technical indicators meet the fully automatic basic standard. The instrument test platform adopts manual lifting (including fast and fine-tuning second gear), but the test process is still automatic testing, calculation and display, providing cost-effective solutions under the premise of ensuring technical indicators.
Features
1. Sensor response, high accuracy, using liquid crystal display
2. Automatically read the surface tension equilibrating value
3. Manual lifting has fast and fine-tuning second gear, simple and reliable operation
4. One-click reset function is accurate and reliable
5. One-click correction with random standard weight, accurate and fast
6. The instrument itself has small errors and can effectively control various errors in the measurement process
7. Using platinum plate method or platinum ring method, can be connected to the computer and optional real-time Linear dispersion software
8. Tensammetric curves over time due to the presence of surfactants can be clearly displayed
9. Linear dispersion and time from low to maximum tension value of two different density liquids interface can be displayed
10. Optional sample thermostatic cup, Thermostatic bath to control the measured liquid temperature
11. Easy to operate
Principle
Measurement principle of Platinum Plate Method or Platinum Ring Method is used to control the contact between the sample and the measurement Probe through a manual lifting platform to automatically test, calculate and display the surface tension value. Linear dispersion can be monitored and recorded in real time when a computer is connected and real-time Linear dispersion software is selected.
Applications
Surface tension measurement, interfacial tension measurement, surfactant research, oil-water interface analysis
Steps
1. Instrument preparation and startup
2. Use the one-click reset function
3. Use one-click correction function with standard weight
4. Select manual lift mode (quick or fine-tuning)
5. Conduct sample measurements
6. Read the automatically displayed tension value
7. Optional connection to a computer for data logging and analysis
Notice
• The instrument adopts manual lifting operation, pay attention to lifting speed control
• The standard weight attached to the calibration should be used
• Make sure the instrument is cleared accurately before measurement
• Optional thermostatic device to control sample temperature
• Power supply voltage requirement is AC220V +/- 10%
• Each grid is 0.02mm when fine-tuning the lift, which requires fine operation
