Features
1.Equipped with 16-bit sample tray, it can work 24 hours without interruption. And all the progress, like the intelligent sample preheating, sampling, measurement, cleaning, drying, result calculation and repeatability calculation are all automatically completed
2.Using photoelectric or thermal detection, which can measure transparent and opaque samples, including gasoline, diesel, kerosene, cutting fluid, heat transfer oil, additives, lubricating oil of new oil and oil in Newtonian fluids.
3.It has the PTC sample intelligent preheating function. It can automatically control the preheating temperature according to the preset test target temperature of the sample to be tested, and the preheating temperature range is between room temperature and 120℃; The preheating rate is 15℃/ min, which greatly reduces the sample constant temperature time during the test.
4.With built-in partier refrigeration system, the constant temperature bath liquid is directly used as the refrigerant to cool down rapidly.
5.The application of bath liquid level adaptive balance technology (patent No. : ZL 2020 2 1531117.X), adapt to the test temperature adjustment, in the process of rising and cooling automatically increase or decrease the constant temperature medium, keep the viscosity tube immersion depth unchanged.
6.Windows operating system with all Chinese interface which is simple operation and friendly human-machine interface. It can access LIMS system and can be connected to the scan code gun, automatic input sample
information.
7.The system has built-in the automatic calibration function of the viscometer constant, as well as auxiliary functions such as temperature calibration, internal clock timing calibration, and automatic conversion of kinematic viscosi-Engler viscosity and automatic calculation of viscosity index.
8.With hardware and software double over temperature protection, over temperature alarm, anti-dry burning protection, lack of cleaning liquid prompt, waste liquid cleaning prompt and other functions to ensure the safe operation of the instrument.
9.Using double glass bath design, PT1000 high precision temperature sensor and double blade stirring, the temperature of constant temperature bath is stable and accurate, and the temperature control accuracy reaches 0.005℃.
10.Automatic intelligent selection test bulb for unknown samples through accurate suction condition algorithm,
you can choose intelligent or follow.
11.With automatic intelligent double solvent cleaning function, the cleaning mode can be customized, and the sample cup can be cleaned while cleaning the viscometer, eliminating the work of cleaning the sample cup separately.
12.With a timing verification port, the instrument can be accurately verified by the standard time verification instrument.
