ASTM D971 ASTM D1331 Surface Tensiometer Interfacial Tension Tester EN 14210 ISO 304 Surface Interfacial Tension test Machine

Easy handle a variety of daily tasks

A. The machine has built-in memory, which is convenient to save multiple sets of data.

B. Password management function to ensure data traceability and prevent data modification and accidental deletion.

C. Real-time display of measurement curves, multiple sets of data can be saved, external printers supported, and Chinese/English exchange operations supported.

Operates without an external PC

BZY100 & BZY200 surface tensiometers use two measurement methods and built-in data memory, so they can be used independently to meet the needs of various purposes. The instrument is lightweight, easy to install, and can be moved quickly.

Application field

1) Oil aging test, especially transformer oil (ASTM D-971)

2) Determination of Surfactant Effectiveness in Wetting Agents and Cleaners Test Surfactant Solution Concentration.

3) Canning approval and cleaning validation in the food industry.

4) Interfacial tension measurements for quality control and optimization of emulsifiers.

5) Cooling lubricant surface tension test.

Extensive data management options

In addition to displaying the results directly on the 4.3-inch touch screen, the BZY100 & BZY200 also provide a wealth of data management options, equipped with easy-to-manage large-space data storage for quick access to all results. In addition, the measured data, together with all important

parameters, can be printed out.

Measurement methods

A. Use the Du Nouy ring method and the Wilhelmy plate method to measure the surface tension and interfacial tension.

B. Manual testing of critical micelle concentration. (CMC)

Ensure compliance with the latest codes and standards

We attach great importance to the repeatability and standardization of the measurement results, the BZY100 & BZY200 are designed to comply with all GB/T, EU, ISO, DIN and ASTM standards for surface

and interfacial tension.
