11. The JK99D1 fully automatic tensiometer can be equipped with a touch LCD screen and a roll type printer, allowing for one click touch operation and real-time display and printing of measurement results without the need to connect to a computer, printer, tedious operation, calculation, or convenient movement;
*The JK99D1 fully automatic tension meter comes standard with PC application software, so it can also be connected to a computer to work for a long time under the Windows operating interface, automatically recording tension change curves, conducting real-time observation, and storing and printing.
*13. The standard configuration includes a circulation insulation platform that can be connected to an external constant temperature bath, with a built-in temperature sensor. Users can easily connect various constant temperature baths by themselves (the instrument does not include a constant temperature bath as standard, users can use the original constant temperature bath or request our factory to provide it).
14. Temperature reading accuracy: 0.1 ℃ (measured by a sensitive temperature sensor), 30%~85% relative humidity.
15. Exquisite structural design, high-precision mobile platform, and precision screw matching servo stepper motor ensure smooth operation, low noise, and more stable lifting of the platform. Equipped with hardware and software one click reset function as standard.
16. Equipped with sensor calibration circle code as standard, the instrument calibration is fast, convenient and intuitive, the data is more accurate, and it is convenient for users to connect with internal/external quality management system requirements.
17. The instrument software has built-in calculation and correction formulas, eliminating the need for tedious calculations. One click fully automatic, completely eliminating human error.
18. According to the actual needs of customers and the teaching process, the measurement can be carried out step by step, and there are mandatory platform lifting and lowering functions in software and hardware
Both the platinum ring method and the platinum plate method can be used to determine the corresponding surface tension and interfacial tension as time and concentration change.
The instrument is not only suitable for measuring almost all low viscosity liquids, but also for measuring most medium to high viscosity liquids, achieving surface interfacial tension testing in industries such as ink, paint, and petroleum.
*21. With fully independent intellectual property rights and a comprehensive after-sales support system, we provide free on-site installation, debugging, and training services, as well as lifelong free software upgrades, to maximize the protection of users' rights to continuous high-quality software and hardware services.
