Automatic Surface Tensiometer, 0-200mN/m, 0.01mN/m, Shanghai HengPing Instrument and meter Co.,Ltd. (CAT#: STEM-AI-0366-YJL)

Automatic Surface Tensiometer, 0-200mN/m, 0.01mN/m, model BZY-2N is manufactured by Shanghai HengPing Instrument and meter Co.,Ltd. BZY series automatic surface tensiometer is a laboratory measuring instrument that uses physical method instead of chemical method to measure liquid surface/interfacial tension. It can quickly and accurately test the tension value of various liquid-gas surfaces and liquid-liquid interfaces. It adopts an electromagnetic force closed-loop force measurement system, single-chip microprocessor control, automatic measurement, easy operation, high test result accuracy, high stability, high repeatability, and high linearity.

Compared with other surface tensiometers, BZY series surface tensiometers have the following advantages:
Fully automated measurement, reducing human error to the lowest level;
Automatically read the surface tension balance value;
One-key reset (any value between 0-400mN);
One-key calibration, with the standard weights attached, accurate and fast;
The platinum plate method is used, which makes it possible to perform measurements in the following environments:
Changes in surface tension values at different times due to the presence of surfactants
Measurement of high viscosity liquids (automatic reading of balance)
The value of the interfacial tension between two immiscible liquids, such as oil and water.
The sensor is responsive and accurate, making it possible to achieve good repeatability and thus provide comparable data.
Simple operation, no need for any external computer control;
The error caused by the machine itself is small, and various errors in the test process are more effectively controlled;
Optional sample constant temperature cup, sample temperature detection device and external constant temperature bath. Test method: Platinum plate method (or platinum ring)
Operation mode: the sample stage is automatically raised and lowered, and the automatic measurement
