CHINA JY-82C automatic video contact angle Tester

Introduction

The titration system of the JY-82C fully automatic video contact angle meter is controlled by a double stepper motor (up and down stroke is 100mm, control accuracy is 0.01mm), which can realize automatic positioning, automatic titration, and automatic reset of the titration system. The syringe adopts high-precision Syringe, Luer locking head, removable needle, convenient titration, high accuracy, fully automatic sample injection, accuracy is 0.01ul, drop volume can be set arbitrarily, software tests the size of droplets in real time, and records The size of the droplet volume.

The main function

Contact angle measurement method (automatic quantitative dripping, dripping accuracy: 0.1ul, fully automatic real-time test):

Static droplet method, (using Opencv graphic contour analysis software to automatically test the left corner, right corner and average angle of the droplet in real time), provides real-time test curves and test data Excel list, with image saving function.

Dynamic test, turn and drop method (dynamic test: advance angle, retreat angle, tilt angle ) (using Opencv graphic contour analysis software, real-time automatic dynamic analysis to obtain advance angle, retreat angle, tilt angle)

Bubble method, the contact angle test of the test material immersed in liquid.

Measuring surface tension:

Hanging drop method (measuring interfacial tension (can test dynamic interfacial tension), CMC (hanging drop method).

Observe and measure the shape and size of the droplets (hanging drop method) and test the surface interfacial tension value of the liquid. The test range of the tension is: 0.001mN/m~1000mN/m).

Features

• 0.7-4.5x high-definition industrial grade continuous zoom microscope;

• It has a dense LED adjustable industrial-grade backlight plane parallel light source to ensure high image clarity without distortion;

• It has video recording function and video call analysis function, and the recording speed of the camera can be selected (in the range of 14~700 frames per second);

• You can arbitrarily set the time to collect images, collect images regularly, and have the entire video recording function;

• The stage is controlled by a stepper motor and can move in three dimensions, enabling multiple tests on one sample;

• An industrial digital black-and-white camera is used for image collection, which can continuously zoom and continuously adjust the brightness of the image. The collected image has high definition, which improves the accuracy and accuracy of the measurement data. It can be monitored in real time and captured at any time. The capture time can be set arbitrarily;

• The instrument uses a USB port, which is simple to install and easy to use. The instrument uses the JY-82 video test system suitable for WINDOWS 64-bit operating system. The system is user-friendly, simple to operate, and convenient to test. It has test reports, which can be saved, retrieved, and printed. ;

• Powerful database management functions make it easier to save data, query and export data;

• All measurement data can be exported as WORD documents and BMP standard format picture files to facilitate data processing;

• Samples of any size can be tested. Sheet or special-shaped samples can be measured and equipped with corresponding fixtures. Extra large sizes require special customization;

• The surface free energy estimation models of solids can be obtained: Fowkes, extended Fowkes, Owens-Wendt, van OSS, Wu harmonic average method, equation of state method, which can be applied to polar, non-polar, low-energy and high-energy solid surfaces respectively. Analysis, calculate the liquid-solid interfacial tension (rsl) and solid surface tension (rsg) based on the contact angle of the liquid to the solid (θ), and generate an experimental report, which can be saved, retrieved, and printed.
