Full Automatic Kinematic Viscosity Tester (Dual Baths)
Full Automatic Kinematic Viscosity Tester (Dual Baths) TT-445Z-1
Full Automatic Kinematic Viscosity Tester (Dual Baths) TT-445Z-1 complies with the ASTM D445 Standard Test Method for Kinematic Viscosity of Transparent and Opaque Liquids (and Calculation of Dynamic Viscosity).
Full Automatic Kinematic Viscosity Tester (Dual Baths) TT-445Z-1 is utilized to test the viscosity of liquid petroleum products, both transparent and opaque, by measuring the time for a volume of liquid to flow under gravity through a calibrated glass capillary viscometer. The dynamic viscosity, η, can be obtained by multiplying the kinematic viscosity, ν, by the density, ρ, of the liquid, under certain constant temperature conditions. The range of kinematic viscosities covered by this apparatus method spans from 0.2 to 300,000 mm2/s at all temperatures.
1. Equipped with a 16-bit sample tray, capable of continuous operation throughout the day. Features intelligent functions for preheating, injecting, measuring, cleaning, drying, calculating results, and repetitive calculations.
2. Provides independent temperature control for each bath, allowing simultaneous testing, cleaning, and drying operations for the corresponding bath.
3. The apparatus utilizes photoelectric or thermal detection methods, enabling measurement of both transparent and opaque samples. This includes Newtonian fluids such as gasoline, diesel, kerosene, cutting fluid, heat conducting oil, additives, fresh, and in-use lubricating oils, among others.
4. Includes a PTC sample intelligent preheating function, automatically controlling preheating temperature based on the expected temperature of the sample. The preheat temperature range extends from room temperature to 120℃, with a heating rate of 15℃/min, significantly reducing sample thermostatic time during testing.
5. Incorporates a built-in Peltier refrigeration system, utilizing thermostatic bath liquid as a cooling medium directly, ensuring fast cooling speed.
6. Applies self-adaptive liquid level balance technology, capable of adjusting to large-span adjustments of test temperature. This feature automatically increases and decreases thermostatic medium during heating and cooling processes, maintaining the same immersion depth.
7. The apparatus features a built-in Windows operating system for easy operation and can be connected to LIMS systems and barcode scanners for automatic input of sample information.
8. Includes a system with built-in automatic calibration functions for the viscometer constant and temperature calibration. Additionally, it offers internal clock timing calibration and can convert Kinematic viscosity into Engler viscosity and automatically calculate viscosity Index and other functions.
9. Offers overtemperature protection functions for both software and hardware, including over temperature alarm, dry heat protection, cleaning solution insufficient prompt, waste liquid cleaning prompt, and other safety features to ensure safe operation.
10. Designed with a double glass bath configuration, PT1000 high precision temperature sensor, and double-blade stirrer, ensuring the thermostatic bath remains stable and accurate, with a temperature precision of 0.005℃.
11. Features an automatic intelligent dual solvent cleaning function, with customizable cleaning modes.
12. Equipped with a timing verification port for accurate time verification through a standard time calibrator.
