Frequently Asked Questions for Viscometers in 2022

1. Question: Is there an absolute viscometer, the one that does not need to be calibrated, we need an absolute viscometer, and we already have a relative viscometer?

     Answer: Hello, the absolute viscometer mentioned here includes Rotational Viscometer and capillary kinematic viscometer. All of our products are Rotational Viscometers, which measure dynamic viscosity, and they all belong to absolute viscometers.

2. Question: Hello, is there any Larley viscometer for sale? It is a test method to test the viscosity of resin. We have Aimer Rotational Viscometer, but it is inaccurate to measure high viscosity. 

     Answer: Hello, yes. Raleigh viscometer = falling stick viscometer, the same product is called differently.

3. Question: Is the KU viscometer the Stormer viscometer?

     Answer: Hello, yes, the unit of measuring viscosity value of Stormer viscometer is KU, so it is also called KU viscometer.

4. Question: The viscosity of the tested paint samples ranges from hundreds to tens of thousands, but what I need to test is the comparison of different viscosities under high shear and low shear. Is it better to use a cone-plate viscometer or a Rotational Viscometer? ?

     Answer: Hello, Rotational Viscometers are divided into cone and plate viscometers and rotor viscometers. The shear force of the rotor viscometer can only reach 2 or 3 hundred. Moreover, they are mostly less than a few dozen, and it is not very good to compare the viscosity under high-low shear force. However, the cone-plate viscometer can test the shear force of thousands of dollars. The industry's basic detection of high-low shear force Use a cone and plate viscometer.

5. Question: Why does the model I read belong to the coaxial cylinder rotary viscometer, but how do I see it is a rotor viscometer?

     Answer: Hello! The coaxial cylinder Rotational Viscometer is also a rotor Rotational Viscometer. Conventional rotor Rotational Viscometer, we call it "coaxial single cylinder Rotational Viscometer", it is a rotor extending into the material to directly measure the viscosity. The coaxial cylinder viscometer adds a set of accessories on the basis of the standard configuration of the ordinary viscometer. This accessory is generally a small amount of sample adapter or an ultra-low viscosity adapter, so this set is called a coaxial cylinder Rotational Viscometer. , is actually a coaxial double cylinder Rotational Viscometer.

6. Question: What kind of viscometer is better for measuring the viscosity of epoxy resin coating?

     Answer: Hello! Viscosity cups or viscometers are generally used to measure coating viscosity. Viscosity cups mainly measure relative viscosity, and viscometers measure dynamic viscosity. In general, except for thixotropic coatings, 4 cups can be used for coatings under 150s, and 1 cup can be selected for coatings under 20s. ISO outFlow Cups are used to measure the viscosity of Newtonian liquid coatings, and architectural coatings are measured with a Stormer viscometer. Viscosity, for all brush-applied coatings, can basically be measured with a Rotational Viscometer or a cone-plate viscometer. .

7. Question: Hello, I would like to know something about the viscometer here. I would like to know about the viscometer used for glue to test the glue sample for less than 1ml, the viscosity is 100-5w cp is there any suitable viscometer recommended?

     Answer: Hello! This can only be used with a cone-plate viscometer, and the measurement results of different brands will be quite different.

8. Question: How long does it take to warm up for Brookfield Digital Viscometer DV2TLV?

     Answer: Hello, after turning on the power switch of the viscometer, preheat the instrument for 10 minutes before automatic zeroing.

9. Question: Can all cone and plate viscometers be used for testing in the GB/T9751 standard?

     Answer: Hello! Not necessarily, please post the relevant parameters and price, and I will recommend the cone-plate viscometer to you.

10. Question: Why does the Stormer viscometer I bought from you stop automatically?

       Answer: Hello, the Stormer viscometer you are using has an over-range automatic shutdown function, check if it is over-range.
