Introduction: YW-200B micro-controlled fully automatic liquid surface tension meter and interfacial tension meter are newly developed products of Chengde Jinhe Instrument. It is controlled by a microcomputer and the newly developed data acquisition software collects the data of the lower computer. The lower part of the machine is uniquely constructed, durable, beautiful appearance, high degree of automation, accurate test results, and strong repeatability. JYW-200B Micro-controlled Automatic Liquid Surface Tension Tester and Interfacial Tension Tester use SY-T5370 "Measurement Method for Surface and Interfacial Tension", GBT 18396-2001 "Natural Latex Test for Measuring Surface Tension", GBT6541-86 "Petroleum Product Oil and Water" The interfacial tension measurement method (the ring method) and the "QB-T 1323-91 Detergent Surface Tension Measurement Ring Pulling Liquid Film Method" and other standards are designed to meet various liquid surface tension and interfacial tension tests. Immediately after the test is completed, the test results are displayed, and the results of multiple test results can also be automatically averaged. This is a highly functional, cost-effective meter and interfacial tension tester. The test software has functions such as automatically drawing test curves, auto-zeroing, automatic ASTM D-971 formula correction, saving test results, generating test reports, etc. The interface is intuitive, simple to operate, easy to learn and use. Features: 1. The ring method test method adopts the scientific tension value correction method. In order to eliminate the errors caused by the platinum ring shape and pollution in the ring test, the correction is no longer based on the gravity method. Instead, two standard substances are used for correction. When the platinum ring is used for a long time, its shape changes, or its shape changes. When it is contaminated and a test error occurs, it can be returned to normal as long as the standard substance is used, without having to replace the expensive platinum ring. 2. The use of integrated molding shell, argon arc welding process, the entire support structure without screws to ensure the stability of the support structure. 3. Adopt low noise, low speed DC motor to drive internal screw structure. Lifting shaft adopts oil-free self-lubricating bearing for precise fit. Vibration during testing is minimal and no shaking. Reliability and durability are greatly improved while ensuring test accuracy. 4. It adopts 32-bit ARM high-end single-chip microcomputer control, which has fast calculation speed and high operation precision. It also adopts a specially compiled filtering algorithm to ensure the stability and accuracy of the indication value. 5, using the United States ADI's high-grade 24-bit AD converter, conversion speed, force value acquisition more accurate. 6. The improved torsion screw lever structure makes the sensor core movement trajectory as close as possible to the straight line, ensuring the linearity of the test. 7, using domestic high-end LVDT displacement sensor, good linearity, the output signal is sensitive, the impedance matching is accurate, to ensure the repeatability of the test 8, the instrument with automatic stop function, when testing the surface tension can be set to automatically stop, after the completion of the elevator will automatically stop the movement and display the tension value. 9. The unique automatic averaging function can automatically average and display multiple test results, reducing the operator's workload and work intensity. 10, the lower computer with a digital LCD screen and keyboard, can be directly operated by the lower machine, while the operating state is directly reflected to the computer side, to achieve two-way control of the computer and lower computer. From the computer, the lower computer can work independently. Technical Parameters: 1, the measurement range: 0 ~ 200.0mN / m 2. Resolution: 0.01mN/m 3, indication accuracy: ≤ ± 1% FS. 4, repeatability error: ≤ ± 1% FS. 5, sample stage travel: >35mm 6, the sample table movement speed: about 15mm/min 7, the whole weight: 7.5Kg 8, power supply: 220V 50HZ 9、Outer size: 300×300×400(mm)
