The first question is, "What are Liquid Properties?" Are they some kind of underwater real estate?

At first glance, viscosity seems pretty straightforward: it tells you how thick a liquid is, or how easily it flows. Case closed, right?

As followers of these rants know, we manufacture and distribute tensiometers. As a
tensiometer manufacturer, we are often asked, “if I am going to replace my tensiometer, which one should I get?”

At first glance, viscosity seems like a fairly simple concept. It helps describe how thick a product is, or how well it flows. That's all, right?
In reality, there are several different terms that come under the heading of viscosity. These terms are derived from how the viscosity is measured. When people talk about viscosity, they are talking about one of two things: kinematic viscosity or dynamic viscosity.
It's not easy to find a lot of information on the differences between dynamic and kinematic viscosity. This is my attempt to bring clarity to these two principal concepts.

I keep running into this kind of thing.
There is a recurring question we are asked as instrument manufacturers:
"Is my equipment working OK?"
This is of particular concern when a production process seems to be off standard.
QC says: "Clearly Process Problems"
Production says: "Bad Test Results"
These challenges arise often.
What to do?

Definition of a Tough Consistency Instrument
Sometimes we encounter a product that is so simple and rugged that it would be tempting to deem it indestructible. Consider a stainless steel trough with a gate and etched numbers on the bottom. Seems simple and the stainless would make it tough, right? That is not the case, but it has survived nearly unchanged for more than 85 years.

One of the most frequently asked questions we get is, "How can I get a viscosity reading from the Bostwick Consistometer?" The answer is, "You can't." We've elaborated on this in other articles. We've even got a great infographic to explain the difference. With this article, I hope to advance the understanding of the difference between these concepts even further.

Customers Want Bostwick Consistometer Calibrations.
When told that CSC Scientific does not calibrate Bostwick Consistometers, people ask . “Then how can I calibrate my consistometer and where can I get a calibration standard?”.
