Cara Pengukuran Viskositas Menggunakan Viscometer Brookfield

Summary

This video demonstrates the process of measuring viscosity using a Brookfield viscometer, presented by PT Transindo Utama Sinar Perkasa, the exclusive distributor of Brookfield in Indonesia. The procedure involves setting up the viscometer, including connecting power cords, adjusting leveling scrubs, and calibrating the equipment. It also highlights how to properly attach and detach spindles to avoid damage, and the correct method for testing liquid soap samples. Key points to note during measurement include sample temperature, volume, and spindle speed. The video concludes with a reminder of important factors to record and how to contact the distributor for further inquiries.

Takeaways

• 😀 Ensure the power cord is properly connected to the power source before starting the viscometer.
• 😀 Remove the shipping cap from the viscometer to ensure proper functioning.
• 😀 Confirm that the temperature probe is correctly installed before beginning measurements.
• 😀 Adjust the leveling scrub so that the water pass is centered for accurate calibration.
• 😀 No spindle should be attached before performing the auto zero process to avoid errors.
• 😀 Always use a 600 ml beaker with 500 ml of the sample for accurate measurement.
• 😀 Immerse the spindle at a 45° angle to prevent air bubbles from being trapped under the spindle.
• 😀 Lift the coupling net when installing or removing the spindle to avoid damaging the pivot point and jewel bearing.
• 😀 Install the spindle by turning it clockwise and remove it by turning counterclockwise.
• 😀 Measure viscosity when the torque percentage is between 10-100% and the spindle has made at least five rotations.
• 😀 Record key parameters including sample temperature, container size, spindle number, RPM, and measurement duration for proper analysis.

Q & A

What is the main focus of the video?

The video focuses on explaining how to measure viscosity using a Brookfield viscometer.

What is the first step in using the viscometer?

The first step is to connect the power cord to the power source and remove the shipping cap from the viscometer.

How should the temperature probe be installed?

The temperature probe should be installed correctly on the Godlike to ensure proper operation.

What is the purpose of adjusting the leveling scrub?

The leveling scrub is adjusted to ensure that the water level indicator is centered during the setup.

Why should there be no spindle installed before performing the auto-zero process?

No spindle should be installed to allow the auto-zero process to complete correctly.

What sample is used in the video for viscosity measurement?

The sample used in the video is liquid soap.

What is the recommended container size for the sample?

A 600 ml beaker is recommended, with 500 ml of sample volume.

What is the proper procedure for attaching the spindle to the viscometer?

To attach the spindle, lift the coupling nut, insert the spindle, and rotate it clockwise. To remove it, lift the coupling nut again and rotate the spindle counterclockwise.

What should be done to prevent air from being trapped under the spindle during measurement?

The spindle should be immersed at a 45° angle to prevent air from being trapped beneath it.

What key factors should be recorded when measuring viscosity?

The following factors should be recorded: sample temperature, container size, sample volume, spindle number, speed (RPM), viscometer model, measurement duration, and whether the test was conducted with or without a temperature probe.
