The measurement of water activity or equilibrium relative humidity (ERH) is a key parameter in the quality control of moisture sensitive products or materials. If there is too much water in a product, there is a risk of microbial growth and water migration. This can lead to clumping, changes in consistency and reduced shelf-life. Manufacturers of foods and pharmaceutical products must, for example, show to the FDA that the water activity of a product has declined to such an extent that bacteria can no longer grow.
For water activity measurements in bulk materials such as flour, grain, spices, etc. For solid and pasty products such as meat, sausage as well as oils, fats, etc.
The station probe HC2-AW-USB offers new possibilities. The USB probe can be directly connected to a PC running HW4-P-QUICK-Vx software enabling water activity measurement capability. The HC2-AW-USB is the perfect device for a multi station application, as multiple probes can be attached to a single PC.

With AwTherm, ROTRONIC offers a professional, high-end laboratory unit for temperature-stabilized measurement of water activity in the foodstuffs, cosmetics, or pharmaceutical industries.
The Rotronic HygroLab is an innovative high-end laboratory analyzer for water activity measurements with up to four measurement probe inputs. Simultaneous or asynchronous measurement with the tried-and-tested AW Quick measuring function for pharmaceutical products, tobacco, coffee, food and many more.
In many situations it can be very useful to measure water activity in production or storage rooms, e.g. inspection of bulk materials to ensure they meet specifications. The HygroPalm 23-AW-A is ideal for measuring water activity in production processes such as random checks of cheese, meat, tobacco, building materials, animal feeds, bakery products, paper, medicines, horticulture, agriculture, etc.
The HygroPalm AW sets are the perfect solution for on-site measurements. They are supplied in a tough, lightweight ABS carry case and include everything needed for measurement and calibration.

The disposable sample containers ensure the optimum sample volume is introduced into the WP-14-S sample holders. They prevent the sample holders from coming into direct contact with the product being tested, thereby preventing soiling or cross contamination. The sample containers also provide a convenient means of collecting and storing samples. Disposable sample containers 14 mm
