Overview
FANGRUI BZY-201 surface tensiometer is a high-performance weighing Sensor using the principle of electromagnetic force equilibrating, with accurate measurement and excellent repeability. The instrument uses both platinum plate method and platinum ring method. Except for the manual operation of the lifting platform, the rest of the functions and performance are the same as the QBZY series automatic surface/interfacial tension instrument, which has a high cost performance.
Features
1. Platinum plate or platinum ring test principle, easy to operate.
2. Automatic digitalization measurement reduces human operation error.
3. Full scale clearing: one-click clearing, instant completion, zero without drift.
4. Full scale automatic correction: the data is accurate and reliable, and the repeability is excellent.
5. When the platinum plate is tested, the displayed value is the surface/interfacial tension value of the sample, which does not need to be calculated again; when the platinum ring is tested, it has a peak holding function, which needs to be calculated by Excel or automatically converted by data processing software.
6. The instrument is compact and works independently, without the need for any additional equipment (e.g. external computers, etc.).
7. Can measure the change of the surface tension of the sample due to time (especially when there are surfactants or volatile matter, limited to platinum plate test mode).
8. Automatically measure medium and high viscosity liquid samples and obtain accurate equilibrating results (limited to platinum plate test mode).
9. Measurement of interfacial tension between disphase mixed liquids such as oil/water interface.
10. It can completely replace the traditional mechanical surface tensiometer.
11. In addition to manually controlling the lifting of the sample platform, the main structure and technical parameters are similar to those of the QBZY series, featuring high-quality design, economical price, and high cost performance.
Principle
The FANGRUI BZY-201 surface tensiometer is based on the principle of electromagnetic force equilibrating, and accurately measures the force on the liquid surface or interface of the platinum plate or platinum ring through a high-performance weighing Sensor to calculate the surface tension or interfacial tension value.
Applications
The instrument is suitable for areas where the measurement of liquid surface tension or interfacial tension of dismixed liquids such as oil/water is required.
Standards
The data did not mention specific compliance criteria.
Steps
The information does not provide detailed operation steps.
Notice
* In platinum plate test mode, it can measure surface tension over time and medium and high viscosity samples.
* In platinum ring test mode, the measurement results need to be converted by Excel or data processing software.
The instrument is equipped with Draft Shield.
* For thermostatic measurement (5~ 90 ℃), Thermostat and thermostatic pool are required separately.
