The Engine Oil Apparent Viscometer is a specialized testing instrument designed in strict compliance with technical standards such as GB/T6538 and ASTM D5293. It is primarily used to determine the low-temperature dynamic viscosity of engine oils, a critical parameter for assessing oil fluidity in cold environments.
This device accurately measures the apparent viscosity of oil samples across a temperature range of -35°C to -5°C, in 5°C increments, providing reliable data for product development and quality control.
Computer-Controlled Operation
Powered by a Windows-based system, the instrument offers stable performance and an intuitive user interface, making it easy to operate even for complex test sequences.
Efficient Cascade Refrigeration
Featuring imported compressors and advanced cascade refrigeration technology, the system ensures rapid cooling, excellent temperature stability, and a long service life.
Factory Calibration with Standard Oils
Before delivery, the viscometer is calibrated using 12 types of imported Kaineng standard oils from the United States. This ensures high curve accuracy across all test points from -35°C to -5°C, with current values and database settings pre-configured at the factory.
Automatic Injection – After placing the sample into the container bottle and setting the target temperature, simply click “Start” to begin automatic sample injection.
Automatic Temperature Control – The system rapidly cools to the set temperature and maintains it with high precision.
Automatic Speed Detection – Once the target temperature is reached, rotation begins for 60 seconds, with real-time rotational speed monitoring.
Automatic Viscosity Calculation – Upon completion of the test, the internal program computes the viscosity value without manual intervention.
Automatic Temperature Rise & Data Saving – After testing, the stator and rotor temperatures rise quickly to facilitate the next test, while all data is automatically saved.
Automatic Cleaning – Equipped with a waste liquid bottle, the instrument performs an automated cleaning cycle after each test.
