Overview
PINGXUAN PXSYD-265B kinematic viscosity meter is a Benchtop all-in-one machine that meets the requirements of the People's Republic of China industry standard SY/T5651 "Technical Conditions for Petroleum Product Kinematic Viscosity Testers". It is suitable for measuring the kinematic viscosity of Newtonian liquid petroleum products at constant temperature in accordance with the national standard GB/T265 "Petroleum Product Kinematic Viscosity Determination Method and Dynamic Viscosity Calculation Method".
Features
1. Adopt a total of five temperature control forms of 20, 40, 50 and 80, and the temperature control accuracy reaches +/- 0.01 ℃.
2. Imported acrylic Glass bathtub, good thermal insulation performance, clear sample observation.
3. Adopt Benchtop all-in-one machine design, the instrument has good integrity and is easy to use.
4. Use electric stirringdevice to ensure uniform temperature in the bathtub.
5. Using intelligent liquid crystal display temperature controller, rapid temperature control, fast Response, small overshoot.
6. The control switch is in the form of a touch key, with a novel design, a compact structure, and a beautiful appearance.
7. Full spray treatment, durable; ultra-thin LCD temperature controller, novel and excellent.
Principle
The instrument precisely controls the working medium (such as thermostatic bath liquid) in the bathtub at the set temperature through electric heating and intelligent temperature control system. The built-in powerbasic stirrer continuously stirres the medium to ensure uniform temperature. During the test, the Capillary Viscometer containing the sample is immersed in the thermostatic bath. After the temperature reaches equilibrate, the time required for the sample to flow in the capillary tubing is measured. The kinematic viscosity value of the sample can be calculated by combining the Capillary constant.
Applications
Determination of kinematic viscosity of liquid petroleum products (Newtonian liquids)
Standards
SY/T5651 "Petroleum product kinematic viscosity tester technical conditions", GB/T265 "Petroleum product kinematic viscosity measurement method and dynamic viscosity calculation method"
Steps
1. Turn on the power supply, turn on the "power" switch, the instrument starts to work, and the medium in the bathtub starts to heat and stir.
2. Set the test temperature and the constant of the capillary tubing used through the instrument button.
3. After the temperature is stable at the set test temperature point, the test can be started.
4. When performing viscosity test, press the timing button to start timing, and then press the stop timing, the instrument will automatically calculate the kinematic viscosity value.
Notice
• When booting, be sure to connect the power cord first, and then turn on the instrument power switch; when shutting down, be sure to turn off the instrument power switch first, and then disconnect the power cord.
• The rotor used for testing (here should refer to the Viscometer accessory, mentioned in the data) needs to be cleaned after use and neatly placed in the special rotor box.
• Keep the connection between the rotor and the shaft clean to avoid staining the sample.
• When the instrument is not used for a long time, a protective cap should be placed on the bottom of the rotating shaft.
• The instrument needs to be calibrated regularly with standard silicone oil to ensure measurement accuracy.
• When turning on the machine daily, check whether the model displayed by the instrument matches the label on the back, and observe whether the torque display after automatic zeroing is normal.
• Avoid using unstable power supplies to prevent damage to the circuit board due to excessive voltage in an instant.
• Before performing automatic zeroing, make sure that the rotor has been removed from the shaft and is not immersed in the sample, otherwise it may lead to a zeroing error.
• When selecting the measurement rotor and Rotation speed, it should be reasonably matched to avoid displaying errors due to exceeding the Measurement range.
• Be careful when operating to avoid bending the rotating shaft due to collision.
