BZY-1

Liquid surface/interfacial tensIon Meter

Introduction

BZY series automatic liquid surface/interfacial tensIon Meter is a laboratory measuring instrument that uses physical methods instead of chemical methods to measure liquid surface/interfacial tension. It can quickly and accurately test the tension values of various liquid-gas surfaces and liquid-liquid interfaces. . Widely used in petroleum, chemical, pharmaceutical, printing, textile, electric power and other industries.

BZY series automatic surface/interface tensIon Meter adopts a professional electromagnetic force closed-loop force value measurement system, single-chip microprocessor control, automatic measurement, easy operation, excellent performance, high-precision test results, high stability, high repeatability, High linearity. The patent number of the surface/interfacial tensiometer is: 200520039453.1. The test method of the surface/interfacial tensiometer: Platinum plate method (or platinum ring) The operation mode of the surface/interfacial tensiometer: automatic lifting and lowering of the sample table, fully automatic measurement

Features

Compared with other Surface Tensiometers, BZY series Surface Tensiometers include but not limited to the following advantages:

Fully automated measurement to minimize human error;

Automatically read the surface tension balance value;

One-key reset (any value between 0-400mN), very correct;

One-button calibration, with the standard weight attached to the machine, accurate and fast;

The platinum plate method is adopted, which fully complies with the requirements of the basic principles of the Wilhelmy platinum plate method, thus providing the possibility to carry out measurements in the following environments:

Changes in surface tension values over time due to the presence of surfactants

Measurement of high viscosity liquids (automatic reading of balance value)

The interfacial tension value between two immiscible liquids, such as oil and water.

Sensitive sensor response and high precision make it possible to achieve good repeatability and thus provide comparable data.

Simple operation, without any external computer control;

The error caused by the machine itself is small, and various errors in the testing process can be controlled more effectively;

Sample constant temperature cup, sample temperature detection device and external constant temperature bath can be selected.

Application

The basic function of tensiometer is to test the surface tension of liquid and liquid-liquid interfacial tension. Surfactants are widely used in all walks of life. Surfactants have functions such as emulsification, solubilization, decontamination, and defoaming. The main Applications are introduced as follows:
