The tester application
Mask material liquid surface tension tester is suitable for determining the surface tension of mask surfactants, organic solvents and mixed liquids containing one or more surfactants and pure liquids or solutions.
Mask material liquid surface tension tester technical index
Test mode: platinum ring
Measurement range: 0-400 N/m
Measurement accuracy: 0.01 N/m
Accuracy error: 0.04 N/m
Repeatability error: 0.04 N/m
Specimen constant temperature range: 0-100ºC
Mask material liquid surface tension tester features
1. platinum ring testing principle, simple and convenient operation.
2. automatic digital measurement to reduce human operation errors.
3. full range zeroing: one key zeroing, instantly completed, no drift of zero position.
4. full range automatic calibration: accurate and reliable data with excellent repeatability.
5. platinum plate test, the displayed value is the surface/interfacial tension value of the specimen, no need to calculate again; platinum ring test, with peak hold function, need to be calculated by Exce or automatically converted to surface/interfacial tension value by data processing software.
6. the instrument is compact and works independently without any additional equipment (e.g. external computer, etc.).
7. the ability to measure changes in surface tension of the specimen depending on time (especially in the presence of surfactants or containing volatile substances, limited to the platinum plate test mode).
8. automatic measurement of medium and high viscosity liquid samples and obtain accurate equilibrium results (limited to platinum plate test mode).
9. can measure the interfacial tension between unmixed liquids such as: oil/water interface.
10. can completely replace the traditional mechanical surface tension meter.
11. In addition to manual control of the sample platform lift, the main structure and technical parameters of this series of instruments are similar to the QBZY series, with high quality design, economic price, and particularly high cost performance.
