Kinematic viscosity is one of the fundamental parameters used to characterize the flow behavior and quality of petroleum products, including lubricating oils, fuel oils, and transformer oils. It directly affects product performance and determines application suitability.
Kinematic viscosity testing requires precise temperature control and accurate timing measurement under strictly defined conditions.
The Fully Automatic Kinematic Viscosity Tester is designed to perform standardized viscosity measurements with minimal operator intervention. The system integrates sample loading, measurement, discharge, cleaning, and drying into a fully automated workflow, supporting laboratory and industrial quality control applications in petroleum, petrochemical, and inspection sectors.
The instrument adopts an advanced fuzzy PID temperature control algorithm to achieve stable thermal regulation with a resolution of ±0.01°C.
It supports multiple standard temperature points (20°C, 40°C, 50°C, 80°C, 100°C) as well as user-defined settings within the range of ambient temperature to 120°C.
This enables compliance with a wide range of petroleum product testing requirements and also allows use as a precision constant-temperature bath.
The system supports simultaneous testing of two capillary viscometers under identical temperature conditions.
Each channel supports 1–8 repeated measurements. Built-in statistical processing follows standard calculation rules, automatically excluding out-of-tolerance results and calculating the average value of valid measurements.
This helps improve repeatability and consistency of test results.
The instrument supports a fully automated end-to-end testing process:
- Automatic sample injection into capillary viscometers
- Controlled rise of oil column to measurement position
- Optical detection of flow time
- Automatic discharge of tested samples
- Automatic cleaning of capillary tubes using solvent
- Automatic drying for next test cycle
The system is designed to reduce manual intervention and standardize testing procedures.
The system is equipped with a high-resolution color touchscreen interface with both Chinese and English language support.
Test results are automatically stored and can be printed via the built-in thermal printer, including key parameters such as test temperature, kinematic viscosity value, and measurement time.
Key technical features include:
- Optical timing detection with 0.1 s resolution
- Timing range: 0 – 999.9 s
- Automatic calculation of dynamic viscosity (based on kinematic viscosity and density at the same temperature)
- Data storage with historical record retrieval
- Traceable test data with time-stamped records
