To create a reproducible measurement of a sample, a large sample quantity is sometimes required. Thanks to the spacious sample chamber of the ClimMate Set, it is possible to easily measure large sample quantities or big sample pieces.
However, this chamber does not have temperature control and the meter does not have humidity equilibrium detection. This battery-powered set is ideal for initial measurement value indications and for portable applications.
Key Features
- Sample container for large samples
- Portable
- Reusable SAL-SC justification standards
Water Activity: What Is It About?
Is my food production at risk of mold or listeria growth? Will my soft gelatin capsules dry out and deteriorate while in storage? Can I extend the shelf life of my products with confidence?
Many question pop-up around the stability of food, cosmetics, pharmaceutical products and pet food. More often than not it is the available water (water activity) that is influential.
Success Stories
Successfully Flowing Into New Market Segments
Though Novasina’s product has been widely accepted in the meat processing segment, in Japan it had not made much headway in other business segments. Novasina needed to identify opportunities in other industries to grow its business presence in Japan.
