PCE Aw value measuring device PCE-WAT 10

The Aw value meter is a powerful instrument that has been specially developed for determining water activity in various materials. With a measuring range of 0.00 to 1.00 aw, this Aw Value Meter offers a wide range of applications, from food to pharmaceutical products and chemical substances.

The Aw Value Meter / Water Activity Meter is equipped with a convenient 99-measurement memory that allows the user to save measurement results for later analysis or comparison. This feature of the water activity meter helps to improve efficiency and traceability in various applications. For real-time measurement, the supplied PC software can be used to transfer the result of the last measurement directly to the PC.

Overall, the water activity meter is a reliable instrument for users who require precise and accurate water activity measurements. Its wide measuring range, high resolution, accuracy and practical features such as the measured value memory and backlit LCD make it an indispensable tool in various industries where water activity monitoring is crucial for quality assurance.

Water activity monitoring is a critical factor in numerous industries, from food manufacturing to materials engineering

Water activity (also known as aw value) is a measure of how much free water is present in a substance to influence chemical or microbial processes. Not to be confused with water content, water activity plays an essential role in the quality control and shelf life of products.

Water activity is usually measured using specialised analysers that determine the partial pressure of water vapour above a sample. Various factors such as temperature, pressure and composition can influence the aw value.

In the food industry, water activity helps to control the growth of microbes and thus ensure the safety and quality of food. In the pharmaceutical and cosmetics industries, the control of water activity is crucial to ensure the stability and effectiveness of products. It also plays a role in materials science and engineering, for example by influencing susceptibility to corrosion.

There are various methods for measuring water activity, such as electronic hygrometry or hair hygrometers. Accuracy in these measurements is essential for reliable quality control.

The importance of water activity cannot be overestimated, especially when it comes to the safety and quality of products. It is imperative for companies in relevant industries to look at implementing water activity monitoring systems to meet today’s standards.
