BZY seriesThe fully automatic interfacial tension meter is a laboratory measuring instrument that uses physical methods instead of chemical methods to determine the surface/interfacial tension of liquids. It can quickly and accurately test the tension values of various liquid gas surfaces and liquid-liquid interfaces. Widely used in industries such as petroleum, chemical, pharmaceutical, printing, textile, and power.

Fully automatic interface tension tester productcharacteristic:

Compared to other surface tensiometers, the BZY series surface tensiometers include but are not limited to the following advantages:

• Fully automated measurement reduces human error to a low level;
• Automatically read the surface tension balance value;
• One click reset (any value between 0-400mN);
• One click calibration, combined with randomly attached standard weights, accurate and fast;
• The use of platinum plate method provides the possibility for measurement 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 equilibrium values)
• The interfacial tension value between two immiscible liquids, such as oil and water

• The sensor has sensitive response and high accuracy, which provides the possibility of achieving good reproducibility and providing comparable data.
• Easy to operate, no need for any external computer control;
• The error caused by the machine itself is small, which enables more effective control of various errors during the testing process;
• Sample constant temperature cup, sample temperature detection device, and external constant temperature bath can be selected.
