Product Description

Based on SIT2000C type spinning drop interfacial tension instrument, it is developed by the improvement of the classic plug-in injector pipe system, anti-corrosion stainless steel heating system and image acquisition. The main characteristics of this product are high temperature pressure resistance, and acid and alkali resistance, H2-type is mud acid resistance. The operation is easier and more stable. The main application areas are: oil EOR (chemical flooding) indoor study and site monitoring; study of surfactants, detergents, emulsions and foams; research fuel oil, lubricants, paints, inks and coatings; pharmaceutical, paper research products, photographic materials, pesticides and so on.
 
 Feature
1, The instrument improves the quartz glass tube pluggable manner, spring thimble against the sample tube, automatically pop up when removing the sample tube easily broken. When injecting the sample into the test again, easier to clean, more convenient operation. Acid and alkali, especially for mud acid and other substances in the oil sector. When injecting the sample into the test again, easier to clean, more convenient operation. Since the inner sleeve made of stainless steel and stainless steel rotor, expansion coefficient of convergence is conducive to temperature conductivity, the material is not susceptible to corrosion and rust, high concentricity, easier to maintain sample tubes horizontally stable, easy to shake.
2, With electric heating temperature control system, capable of constant temperature experiments. The instrument uses a precise PID temperature control technology, heating assembly with a new corrosion resistant stainless steel design, fast heat conduction and easier to uniformly heat the sample tube not need to meet other temperature control devices.
3, Servo motor control system upgrade, motor control and stability;
Of the German imports of US imports of high-speed motor and encoder control technology, servo control system has a complete motor control system upgrades and better compatibility, speed control up to 14,000 rpm / min, speed control accuracy is ± 5 rev / points, the control points up to 500 points, more accurate, more convenient manipulation.
4, Using the latest precision LED control technology while updating the high-speed acquisition and trigger mode CCD image acquisition under low-speed and high-speed rotation conditions are not flashing screen, the image is sharper edge interface, useful for analyzing oil samples turbid fine features.
5, The master program is Windows interface, easy operation, the image as a standard BMP file that can be stored in print. The program uses the world's leading computing technology interfacial tension measured value, simply press the "test", our software automatically controls the speed camera, save the images to calculate interfacial tension value, showing the measured values, the process without human intervention, so as to effectively avoid the human factors on the measured value. You can record the value of interfacial tension with time, speed, temperature changes and all measured values are stored in the database, and export directly to EXCEL documents to be displayed in real-time graph of the measured values. User-friendly software design, powerful database management manages all test data.
6, Low-noise electric viewfinder mechanism interface button operation, simple and convenient. Three leveling design makes it easy to control droplets in the range of available window.
