The kinematic viscosity tester is mainly used to determine the kinematic viscosity of liquid petroleum products (such as lubricating oil, diesel, jet fuel, etc.) at a specific temperature, in centimeters (mm ²/s). Its core function is to measure the flow characteristics of liquid in laminar flow state through a constant temperature control system and capillary counter current method. Its core principle is to measure the time for the liquid to pass through the calibrated capillary at a constant temperature, and calculate the viscosity value by combining the capillary constant. It is widely used in the petrochemical industry, power industry, and scientific research field.
key component
Capillary viscometer: a set of glass capillaries with different inner diameters (such as 0.4mm to 4.0mm) used to adapt to liquids with different viscosity ranges.
Constant temperature control system: using digital PID temperature control technology, the temperature control accuracy can reach ± 0.01 ℃, ensuring temperature stability.
Sensor and timing unit: High precision sensor detects liquid flow, timing unit records flow time, with an error of ≤± 0.01 seconds.
Main Features
Easy to operate: LCD screen displaying Chinese characters, touch sensitive buttons, can set viscosity meter constants, control temperature values and other parameters through the keyboard, and some instruments also have memory function.
High temperature control accuracy: using imported sensors and digital PID temperature control technology, the temperature control range is wide, and the accuracy can reach ± 0.1 ℃ or even higher.
Versatile features: Some instruments have functions such as automatic oil sample extraction, cleaning and drying, calculation and printing, as well as constant calibration, viscosity index calculation, etc. Some models support network communication.
Usability and safety: color touch screen operation, three color light prompt status, easy for beginners to get started. Equipped with over temperature protection and anti dry burning function to avoid instrument damage or safety accidents.
