Overview
BZY-2 liquid surface/interfacial tension meter is a fully automatic laboratory measuring instrument of CNSHP brand. It uses physical methods instead of chemical methods to quickly and accurately test the tension value of liquid-gas surface and liquid-liquid interface. The instrument adopts a professional electromagnetic force closed-loop force value measurement system and a single-chip microprocessor control. It has excellent performance such as automatic measurement, simple operation, High Accuracy, High Stability, High Repeatability and High Linearity. It is widely used in petroleum, chemical industry, printing, Spinning & weaving, electric power and other industries.
Features
1. Fully automated measurement to minimize human error
2. Automatically read the surface tension equilibrating value
3. One-click zero (any value between 0-400mN), very correct
4. One-click correction, with random standard weight, accurate and fast
5. Adopt the platinum plate method, fully in line with the basic principles of the Wilhelmy platinum plate method
6. Sensor responsiveness, high accuracy, good repeability reproducibility
7. Simple operation, no external computer control required
8. The machine itself has small errors, effectively controlling various errors during testing
9. Sample thermostatic cup, sample temperature detection device and external Thermostatic bath
Principle
The BZY-2 liquid surface/interfacial tension meter adopts the platinum plate method (or platinum ring method), which fully conforms to the basic principle of Wilhelmy platinum plate method. The instrument realizes automatic lifting and automatic measurement of the sample stage through a professional electromagnetic force closed-loop force value measurement system combined with a single-chip microprocessor, and can accurately determine the liquid surface tension and liquid-liquid interfacial tension.
Applications
Petrochemicals industry, printing industry, paints Coatings industry, pesticide industry, cleaning agent industry, Eletroplating industry, cosmetics industry, Spinning & weaving industry, food industry, water treatment industry, power industry, biological engineering, research institutes, Universities & colleges
Standards
Wilhelmy platinum plate method
Steps
1. One-click clearing (any value between 0-400mN)
2. One-click correction, with random included standard weight
3. Automatically read the surface tension equilibrating value
4. The sample stage is automatically lifted to complete the measurement
Notice
• Using platinum plate method for measurement
• The measurement of surface tension values at different times due to the presence of surfactants
• High viscosity liquid measurement (automatic equilibrate reading)
• The measurement of interfacial tension between two dissolving liquids
• Optional sample thermostatic cup, sample temperature detection device and external Thermostatic bath
