Description   What's Aw?  
Novasina Water Activity meters
For over 40 years NOVASINA has been specializing on producing measurement instruments running the self-developed electrolytic measuring cell for accurate measuring of the relative equilibrium humidity of materials respectively the water activity (aw-value).  Novasina fully develops and produces precision measuring devices and includes always its long lasting know-how. It's proud of the “SWISS MADE” label, which guarantees customers highest quality, innovation and longevity.

We offer 3 levels of Water activity measurement and meters:

The LabSwift-aw is a new portable device, which allows for an optimal cost efficiency with its measurement speed, accuracy and reproducibility. The optional battery of the LabSwift-aw allows measurement directly at the production line. A data logging function with SD card allows recording of all measurement data and protocols.

About Novasina

The LabTouch-aw, with its ergonomic design and the touch-screen, makes water activity measurements easier than ever before. Semi-temperature-control and active sample temperature measurements, by an integrated infrared sensor, provide the highest possible reliability of measurements.

The new LabMaster-aw is a professional level instrument for highly precise measurements of water activity in food, pharmaceutical, chemical or cosmetic products.  The LabMaster-aw utilizes intelligent resistive electrolyte sensor technology in combination with a precisely controlled temperature chamber. The LabMaster-aw can network with up to nine LabPartner-aw at satellite locations to form an integrated system of water activity instruments

Typical Applications for these reliable units would be:

• Cheese • Fruits • Meats • Pasta • Chocolate • Snack Foods • Pet Foods • Paper • Ink • Pharmaceuticals
