Water activity Laboratory instrument lor accurate water activity (aw) measurement Product safety Microbiological stability

„AM life needs water!" There is no life without water! „ Water means lifef Thanks to water, life has developed and new life „Life needs watei". Water is the „elixir of life" for animals, humans and plants. But bacteria, fungi and viruses also need water to live. Water is stored in every product. Either in the form of a chemical compound with other molecules or as free water, which is stored between the compounds. What is the optimum amount of both types of water now? The amount of bound water is depending on the chemical reactivity of the substances Free water can be affected by production processes...

Novasina, the market-leading provider of accurate water activity measuring instruments Enter the world of water activity! For over 50 years Novasina has been developing globally recognised and accurate water activity measuring instruments for quality and research laboratories. The unique measuring technology is based on an electrolytic aw value measurement as well as on simple operability and sample conditioning. These are the key factors for correct and repeatable measurements. Thanks to new functions, the effective measuring accuracy and reproducibility could be improved and the scope of applications...

The LaòTouch / Click-aw product range With the LabTouch-aw measuring instrument you acquire a long-lasting laboratory device, which is upgradeable at all times thanks to its advanced technology. Extra LabClick-aw's can simply and easily be attached to a LabTouch-aw advanced as additional measuring units. A LaMouch- aw manages and operates up to 2 LabClick-aw using just one cable per chamber. As a result, it is possible to measure up to 3 samples simultaneously. The intelligent network independently recognises a new chamber and correspondingly lintegrates it in the network. An SD-card is used...

a value measurement method The test sample is placed in a completely sealed and temperature- stabilised measuring chamber. After closing the chamber, the sample humidifies or dehumidifies the surrounding air volume inside the chamber by exchanging free water from the sample and humidity from the air. At a certain point, the mass flow of water in each direction is constant, means, equilibrium is reached. At this point, the air humidity is linked to water activity, thus an air humidity measurement can be used to determine the water acitvity of the sample. State-of-the-art instruments are monitoring...

Novasina - Swiss quality, flexibility and competence Since its establishment almost 50 years ago, the Novasina company has specialised in the accurate measuring of air and material humidity. The basis of this was the world's first, self-developed electronic measuring sensor for measuring humidity. This technology is based on the resistive electrolytic measurement principle. This was further developed and optimised over decades. This measuring principle is generally the most demanding and most accurate. Modern substances and materials allow continuous optimisation and expansion of the area of...
