Instrument Features

1Fully automatic wide range kinematic viscometer Configure dual 16 bit sample trays, with intelligent preheating, injection, measurement, cleaning, drying, result calculation, and repeatability calculation all automatically completed.

2Dual bath independent temperature control, dual channel testing, cleaning, and drying can be performed simultaneously.

3By using photoelectric or thermal detection, transparent and opaque samples can be measured, including Newtonian fluids such as gasoline, diesel, kerosene, cutting fluid, thermal oil, additives, lubricants, new oils, and in use oils.

4Equipped with PTC sample intelligent preheating function, it can automatically control the preheating temperature based on the preset test target temperature of the tested sample, greatly reducing the constant temperature time of the sample during testing.

5Built in Peltier refrigeration system, directly using constant temperature bath solution as refrigerant, rapidly cooling down.

6Self developed technology for adaptive balance of bath liquid level, suitable for large-span adjustment of testing temperature, without the need to add or remove constant temperature medium during the temperature rise and fall process.

7Windows operating system, fully Chinese interface, easy to operate, user-friendly human-machine interface, can be connected to LIMS system.

8The system comes with automatic calibration of viscosity constants, as well as auxiliary functions such as temperature calibration, internal clock timing calibration, automatic conversion of kinematic viscosity to Engler viscosity, and automatic calculation of viscosity index.

9It has dual functions of software and hardware over temperature protection, over temperature alarm, anti dry burning protection, lack of cleaning solution prompt, waste liquid cleaning prompt, etc., to ensure the safe operation of the instrument.

10Adopting a double-layer glass bath design, PT1000 high-precision temperature sensor, and double blade stirring, the temperature of the constant temperature bath is stable and accurate, with a temperature control accuracy of 0.01 ℃.

11Equipped with automatic intelligent dual solvent cleaning function, it cleans quickly and thoroughly.

12Equipped with a timing calibration port, the instrument can be accurately time calibrated using a standard time calibrator.
