Introduction
JK99 series automatic tension meter adopts platinum plate method and platinum ring method. It is a simple and easy test instrument that replaces chemical method with physical method. One-button automatic zero adjustment and one-button automatic measurement can be used quickly and accurately. The surface tension of various liquids and the interfacial tension between liquid and liquid were measured.

JK99 series main models

Common features of the JK99 series
1, using high-quality sensors, accurate test data, high precision, good repeatability, long life.
2. Platinum ring/platinum plate method determines the corresponding surface tension and interfacial tension as time and concentration change.
3, JK99B / JK99C / JK99D / JK99M type can be applied to the Windows operating interface, can work for a long time, record curves and store printing.
4, exquisite structure design, the platform runs smoothly, and the noise is small.
5, a set of sensor calibration circle code is standard, the instrument calibration is quick and convenient, the data is more accurate, and the internal control requirements of the user quality management system are docked.
6. The instrument provides manual zero clearing and software one-key clearing. The interval instrument automatic zero clear function can be established according to the customer's needs.
7. According to the actual needs of customers and teaching process, it can be measured step by step. There are forced lifting and lowering platform functions in software and hardware.
8, in line with national standard GBT 22237-2008, GBT 5549-2010 and GBT 6541-86, compatible with the platinum ring method and the platinum ring method, easy to compare user data and different industry standards.
9. Both the platinum plate and the platinum ring in the instrument can measure the surface tension of the liquid and the interfacial tension between the liquid and the liquid.
10, built-in calculation and correction formula in the instrument software, no cumbersome operation, no calculation, one-click automatic data results, completely eliminate human error.
11, JK99F (standard) / JK99C (standard) / JK99D (optional) / JK99M (optional) built-in touch-screen LCD screen easy to operate and display, including roll-type printer, so that it can work independently, easy to move; Key touch operation and instant display, output and print measurement results without connecting to a computer or connecting to a printer.
12, JK99B/JK99C/JK99D)/JK99M can also be connected to computer operation (including application software), automatically record the tension curve for immediate output, and can perform real-time observation and real-time recording.
13, JK99B/JK99C/JK99D)/JK99M type free configuration can be connected to the constant temperature tank circulation insulation platform, built-in temperature sensor, users can easily externally connect various thermostats (the instrument is equipped with no thermostat, the user can use the original The thermostat or our factory is equipped with). Optional power distribution temperature control.
14. The instrument can be used for medium and high viscosity liquid measurement to achieve surface tension test in ink, paint, petroleum and other industries.
15. Complete independent intellectual property rights guarantee the high quality and continuous service of software and hardware. The company's technology and after-sales personnel will serve you wholeheartedly.
