New Water Activity Meter for Laboratory Applications

Mar 11 2016

With AwTherm, ROTRONIC (Switzerland) offers a professional, high-end laboratory unit for temperature-stabilised measurement of water activity in the foodstuffs, cosmetics, or pharmaceutical industries.

The wide control range permits measurements to be integrated directly in the tempered manufacturing or storage process. Water activity measurement reacts very sensitively to variances in temperature. Stabilising the temperature prevents imprecise results due to external temperature infl uences.

A further advantage of AwTherm is that the measuring head is removable, which means that the probe can be temperature-calibrated or adjusted to give high precision.

The AwTherm shows its paces in island-operation mode, with its simple handling and clarity. No laboratory should be without the device in conjunction with the ROTRONIC HW4 software.

The free water in a product influences its microbiological, chemical and enzymatic stability. If there is too much free water present, the products spoil; too little water can be detrimental to the product characteristics.

Measuring water activity provides useful information about characteristics such as cohesion, storage lifetime, clotting or pourability of powders, tablets, etc., or the adhesive properties of coatings.

Features at a glance: ROTRONIC HYGROMER IN-1, Highest precision through exact stabilization of temperature, Wide temperature-control range, Excellent reproducibility, Excellent long-term stability, Variable size of sample container, Reference probe exchangeable for calibration or cleaning, Quickest measurements with the AwQuick function, Simple operation via Touch Interface, and Conforms to ISO 21807 / EMC 2008/108/EC / IEC EN 61010-1:2010.
