Is Test Sieve Certification All You Need?

Posted by Art Gatenby on Oct 29, 2015 1:45:10 PM

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.

LOD is Really Simple, or Moisture Analysis for the Newbie

Posted by Art Gatenby on Jun 12, 2015 4:51:00 PM

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.

Is In-Line Moisture Measurement For You?

Posted by Art Gatenby on Feb 27, 2015 9:59:54 PM

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.

How Wide Is The Moisture Measurement World?

Posted by Art Gatenby on May 13, 2014 6:26:00 PM

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.

How To Fix An Abused Bostwick Consistometer

Posted by Art Gatenby on Apr 2, 2014 2:49:00 PM


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.

How Are Consistency, Surface Tension and Viscosity Different?

Posted by Art Gatenby on Feb 26, 2014 11:35:00 AM

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.
