Kinematic Viscosity Tester

Precise Temperature Control System
The kinematic viscosity tester manufacturer is equipped with a precise temperature control system. By continuously monitoring and adjusting the temperature in the bath, the test temperature is controlled within an error range of ±0.1°C. This characteristic is crucial for viscosity testing, because the viscosity of liquids will fluctuate significantly with temperature changes. A precise temperature control system can effectively eliminate the interference of temperature on viscosity test results, thereby improving the reliability and accuracy of the test.

Corrosion-resistant And Durable Material
The main material of the kinematic viscosity tester is aluminum alloy, which has stable chemical properties and is not prone to chemical reactions with other substances, giving it excellent anti-oxidation and corrosion resistance. Many liquid samples used for testing will contain corrosive components. For example, lubricating oil may contain sulfides, or fuel oil may contain acids. Aluminum alloy materials are not easy to react with them and can effectively resist the corrosion of these liquids, extending the service life of equipment and reducing maintenance frequency. It is suitable for high-frequency testing in laboratories and industrial production environments.

High-precision Capillary Viscometer
The high-precision capillary viscometer equipped inside the kinematic viscosity tester complies with the international standard ASTM D445, ensuring that the diameter and length of the capillary tube are precisely calculated and strictly calibrated. The diameter and length of the capillary tube will directly affect the flow time of the liquid in the capillary tube: Under given pressure and temperature conditions, the smaller the capillary diameter and the longer the length, the longer it takes for the liquid to flow. The precise diameter and length design makes the measurement of flow time more accurate, which can then be accurately converted into the viscosity value of the liquid, thereby achieving high-precision viscosity measurement.

Highly Efficient Automatic Cleaning System
In order to improve testing efficiency, kinematic viscosity tester manufactures are usually equipped with an automatic cleaning system that automatically cleans pipes and sample containers after each test through a preset program to prevent cross-contamination between different samples. The automatic cleaning system uses high-pressure water or solvent for rapid flushing to ensure that the instrument is cleaned and put into use for the next test in a short time. This feature is especially suitable for occasions that require rapid multi-sample testing, such as petroleum laboratories or chemical plants, which greatly shortens the test interval and improves the utilization rate of equipment.

1,Security Design
The kinematic viscosity tester is built with multiple safety features including over-temperature protection, over-current shutdown, and automatic alarm functions. These ensure safe operation during extended testing periods, protecting both the instrument and the user.

2,User Friendly
Designed with the operator in mind, the viscometer features intuitive menus, clear prompts, and easily accessible controls. Users can quickly become proficient with minimal training, making it suitable for both experienced technicians and newcomers.

3,Delicate Structure
The compact and refined mechanical design ensures precise alignment of capillary viscometers and temperature sensors. This delicate construction minimizes vibrations and maintains consistent test conditions for reproducible results.

4,Automatic Printing
Built-in micro printer automatically outputs test results upon completion, including viscosity values, temperature, date, and time. This eliminates manual recording errors and provides immediate documentation for quality records.

5,Simple Operation
With pre-set test methods and one-key start functionality, the operator simply mounts the capillary viscometer, sets the temperature, and initiates the test. The entire process is streamlined to minimize user intervention and reduce the risk of operational mistakes.

6,Easy Operation
The kinematic viscosity tester features a logical workflow with clear visual indicators and step-by-step guidance. Sample loading, temperature setting, and measurement initiation can be performed quickly and intuitively, saving valuable time in busy laboratories.

7,Complete Functions
Beyond basic kinematic viscosity measurement, the viscometer supports multiple calculation modes, automatic timing, temperature compensation, and result averaging. It accommodates various capillary sizes for a wide viscosity range, meeting diverse testing requirements across industries.

8,Soft Light Screen
The high-quality display features adjustable soft backlighting that reduces eye strain during prolonged use. The screen presents clear, easy-to-read information even in low-light conditions, enhancing user comfort and productivity.

1,How does a Kinematic Viscometer work?
It works by timing how long a fixed volume of fluid takes to flow through a calibrated capillary tube under its own gravity. The kinematic viscosity is then calculated by multiplying the measured flow time by a viscometer constant specific to the tube. This measurement is highly dependent on precise temperature control.

2,What is the difference between manual and automatic kinematic viscometers?
Manual viscometers require the operator to time the flow with a stopwatch and perform calculations, which can introduce human error. Automatic viscometers use electronic timing and sensors to detect the flow, automatically calculate the viscosity, and often include features like self-cleaning and data storage, saving time and improving accuracy.

3,What maintenance does a Kinematic Viscometer require?
Regular maintenance includes cleaning the capillary tube and sample chamber after each use to prevent contamination, and periodic calibration with certified viscosity reference standards as recommended by the manufacturer. Proper maintenance ensures the accuracy and reliability of your test results.
