BZY100&BZY200 Surface tensiometer

MesuLab as a leader in the field of interface chemistry in China, has developed various scientific measuring instruments with high precision and intuitive operation concepts. We combine long-term industry experience with high-quality manufacturing technology to achieve high precision and repeatable operation of measuring equipment.

Among them, the surface tensiometers BZY100 and BZY200 are widely used in quality control processes related to surface interfacial tension, such as testing emulsifiers or wetting agents and cleaning agents. It is reliable, easy to use, independent of computers and other equipment, and can provide accurate and reliable analysis when testing a large number of samples.

The high-performance weighing sensor based on the principle of electromagnetic force balance has accurate measurement value and good repeatability.

Platinum plate method and platinum ring method are both used.

Fully automatic measurement, one-click value selection.

Range correction and accuracy correction function to ensure the long-term accurate measurement of the instrument.

Main features of automatic surface tensiometer/interface tensiometer BZY100/BZY200:

BZY100, BZY200 are the upgrading products of BZY-101, BZY-102, BZY-201, BZY-202, etc., and their performance has been greatly improved.

* The 4.3-inch touch screen is adopted, and all operations and information are completed or displayed on the screen;

* Sensor based on the principle of electromagnetic force balance, with high sensitivity, high precision and high repetition; * platinum plate method and platinum ring method;

* Automatic measurement, no calculation, direct display of surface tension or interface tension;

* One-key reset and one-key correction; Digital processing technology, without deviation;

* Users can calibrate data with standard samples (distilled water and pure ethanol) to ensure the accuracy of measurement;

* Real-time display of measurement curves, saving of measurement results, printing of main parameters, data and curves; * Double-door transparent plexiglass windproof cover, easy to operate, reducing the requirements of the use environment; * Password management function, to ensure data traceability, to prevent data modification and deletion by mistake;

* English operating system.

The whole series adopts high-precision electromagnetic sensors. BZY样本-1.png

It is specially developed for testing the surface interface tension. Compared with the traditional strain sensor, it has many advantages, such as high measurement accuracy, good repeatability and little influence by temperature. It is the mainstream testing scheme at present.

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.
