JYW-200B liquid Surface Tensiometer, software control

Introduction

    The difference between model JYW-200A and model JYW-200B: JYW-200A is directly controlled by the host for testing, with a resolution of 0.1mN/m (milliN/m), and this model has strong practicability; JYW-200B in the host control at the same time, the addition of computer software control, the resolution of 0.01mN/m (milliN/m), computer software can display, save, print tension curve and test data report, its function is reliable and excellent.

Directions for use

    After the instrument is unpacked and taken out, put it on the test bench, install the foot, adjust the foot to make the instrument reach a horizontal state, hang the platinum ring, power on and turn on the machine, and it can be used normally. How to use computer software (upper computer): connect the computer with the instrument, install the surface tension measurement software on the computer (any computer can be), and open the software after installation to use the computer for testing and other operations.

Features & Standards (not listed)

    Using micro-control technology, the operation is simple and the intelligence is high; It has the functions of automatic zeroing, real-time display of force value and tension curve, automatic recording of test results, automatic saving and averaging, automatic correction according to ASTM-D971 formula, etc.; The test results are automatically corrected and averaged; Results can be easily displayed, stored, and printed.

    The main machine is designed with SY-T5370 "Surface and Interfacial Tension Determination Method", GBT 18396-2001 "Natural Rubber Latex Ring Method for Determining Surface Tension", GBT6541-86 "Petroleum Products Oil-Water Interfacial Tension Determination Method (Ring Method)", "QB-T 1323-91 Determination of Surface Tension of Detergent Ring Pulling Up Liquid Film Method" JB/T9388, ISO1409 and other standards, which can adapt to the test of surface tension and interfacial tension of various liquids, and adopts liquid crystal digital displayIt is a very high-performance, cost-effective table and interface tension testing instrument.

Application

    Power industry - mainly used to analyze the purity of insulating oil and the pollution status of operating oil;

   Ink and ink industry - mainly used to analyze printing, coating tendency, wettability, and general quality control;

    Detergent industry - mainly to analyze the absorption rate and properties of surfactants, and study the critical micelle concentration;

   Chemical additives industry – for the study of the behavioural capacity to aggregate in diffusion;

   Cosmetics industry – for the analysis of dispersion, stability and wettability of emulsions or suspensions;

    Electroplating industry - mainly to analyze the wettability of electroplating solution and carry out quality control;

    Pesticide industry - the ability to analyze absorption, dispersion, and stabilization;

    Paint and coating industry - also the industry that everyone is more concerned about. It is mainly used for coating tendency, film-forming and dispersion, stability and wetting ability;

    Water treatment industry - to put it bluntly, it is to treat sewage and obtain water quality analysis of various types of water;

    Petroleum production industry – analysis of petroleum drainage aids;

    Fire protection industry - used to analyze the instantaneous spreading, wetting capacity of foam extinguishing agents, etc.

    Universities – used to analyze the interfacial tension characteristics of tables.

Performance characteristics:

• The ring method test method adopts the scientific tension value correction method, and the gravity method is no longer used when correcting, but two standard materials are used for correction, when the platinum ring is used for a long time, its shape changes, or it is polluted, and the test error is generated

• Correction with a reference material can be performed to return to normalcy without having to replace an expensive platinum ring.

• The integrated molding shell and precision direct transmission mechanism are adopted, which greatly improves the reliability and durability of the instrument, and the transmission mechanism has no vibration, which provides a physical guarantee for improving the test accuracy.

• It adopts 32-bit ARM high-end single-chip microcomputer control, fast operation speed, high operation accuracy, and adopts specially compiled filtering algorithm to ensure the stability and accuracy of the indication value.

• The high-end 24-bit AD converter of Analog Devices in the United States is adopted, which has fast conversion speed and more accurate force measurement.

• The improved torsion wire lever structure makes the movement trajectory of the sensor core as close to a straight line as possible to ensure the linearity of the test.

• The high-end LVDT displacement sensor is adopted, with good linearity, sensitive output signal and accurate impedance matching, which ensures the repeatability of the test

• The instrument is equipped with an automatic stop function, which can be set to automatically stop when testing the surface tension, and the lifting table will automatically stop the movement and display the tension value after the test is completed.

• The automatic averaging function can automatically average and display the results of multiple tests, which reduces the workload and work intensity of the operator.

• It is displayed on a digital LCD screen, with real-time values on one side and test results on the other. It is very convenient to read the test results directly.

• The instrument includes a set of genuine computer software. (PC optional)
