II. Application Fields:

Broadly used in the development of novel or blended surfactants, wetting paints and pigments, stable latex, pharmaceutical and cosmetic production, ink flow characteristics, surfactant concentration in electroplating baths, surfactants for biological preparations, oil field surfactants, transformer oil quality testing, synthetic blood penetration tests for surgical masks, and various educational applications.

III. Testing Methods:

Platinum Ring Method, Platinum Plate Method (optional)

IV. Main Technical Parameters:

1) Platinum Ring Gauge Measurement Range: 0 to 200.0 mN/m Resolution: 0.01 mN/m

2) Software zeroing and peak retention

3) Platinum ring radius R9.55, platinum wire rO.3

4) Indicated relative error not greater than ±0.2 mN/m; Indicated repeatability error not greater than ±0.2 mN/m

5) Calculate and derive the average value from multiple tests; precise testing, with good data repeatability.

6) Equipped with a quartz glass beaker, suitable for testing various strong acid and alkali solutions.

7) Computer-controlled operation in automatic mode, compatible with Windows interface, featuring an intuitive user interface, parameter settings, real-time display of test curves, peak hold function, automatic factor correction, and calculation of actual tension values. The machine automatically shuts down upon completion of the test. It includes temperature calibration capabilities. Curve and data saving, printing, and historical curve review and printing can be done automatically on the computer interface. English and Chinese test reports are available (computer and printer can be user-selected).

8) Dimensions: 220×320×450 (mm)
