For several years, people in the test sieving business have been grousing about the difficulty of making sure that a test sieve certification is what they need. Anyone who is working with close tolerances in the smaller particle sizes, like 300 microns and smaller, have serious issues in matching results from test sieve to test sieve.Read More

One quiet night, long ago I was musing over moisture analysis and how easy it is to do using Loss-on Drying (LOD). Little did I know what was in store.Read More
When people hear of viscosity for the first time, invariably they ask these three questions:Read More
Five years ago, we published an article on in-line vs. off-line moisture measurement. At that time we debated whether these measurement systems should be called on-line or in-line. We chose to use the term "on-line". Since then, however, the world of the internet became known as "online". So, to avoid confusion, we changed our view and now refer to direct measurement as "in-line" moisture measurement.Read More
If you take Sieve Shakers for granted, you may be surprised to know that the selection of the right shaker can have a profound effect on your sieving results.Read More
Nearly every day we have a question about differences between Viscosity, Consistency and Surface Tension. There is usually a second part of the question;Read More
When our customers tell me about the different places where CENCO and CSC Digital Moisture balances are used it always interests me.
At one end of the spectrum is the classic Speedy Moisture Tester where you use the reaction of water with calcium carbide to cause a mini explosion resulting in a moisture measurement reading. This method is used frequently for soils, concrete, and other like materials.
Which looks more durable to you?
The value of a Bostwick Consistometer is that it’s easy to use, which makes it simple to do repeatable testing. The Consistometer is made of stainless steel. One would think that this means a long and useful life. However, as I regularly discover, the real world often defies theory.
A Consistometer’s value is diminished if its leveling plate and screws get bent out of alignment. The story that follows tells how people in the real world handle, or mishandle, this instrument, and what can be done to save it.
I used to think that liquids were pretty simple things. Is that what you think too?
Not so fast. Let’s take a look at three properties of liquids and see if we change our view.
