The Bostwick Consistometer is used all over the World to check the quality of sauces and condiments. In our in-house training session we do blind product tests and clearly define the differences between brand of ketchup and mustard. This is a testament to the value placed on Bostwick Consistometer tests by the top food manufacturers.

At one end of the spectrum of the moisture world 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.

Many accessing our web site ask questions such as:
“How does water content affect water activity?”
"How is water activity different from water content?”
”Can I convert from moisture to water activity?”
I previously commented on water activity and now hope to clarify the differences between water activity and moisture content. Given that both of these measurements deal with water connected to a material, we must first understand of water content in a product.

Loss-On-Drying moisture analysis seemed like a simple process until, in a state of naïve bliss, I promised to look at evaporation, vapor pressure and bound water. While I was otherwise occupied with hese realities, I offered to enter the world of witchcraft and folklore; water activity.

Do an internet search for the term “viscosity”, and you’ll find a variety of definitions for the word. For example:
Topics: Viscometers, Viscosity
When people hear of viscosity for the first time, invariably they ask these three questions:

When our customers tell me about the different places where CENCO and CSC Digital Moisture balances are used it always interests me.

As usual when we pose a question, like:
We often get a the reaction, “So Who Cares?” We'll try to answer both questions.

Water activity is the water in a material available to support the growth of microorganisms. Consequently, the measurement of water activity is important in areas such as food processing, pharmaceutical production, products affected by mold, and a host of products that change characteristics when exposed to moisture.

When people are looking for a way to measure small amounts of moisture, we often recommend the Karl Fischer method.
