Rotronic Develops Fast and Precise Water Activity Measurement Products

A water activity measurement product.Water activity in perishable foods and pharmaceutical products has a significant influence on their shelf life and storability. Water activity also has a determining influence on the quality of a product, its stability, taste and aroma. Rotronic offers a complete range of water activity products. The devices are accurate and characterised by their high efficiency, exchangeability and ease of calibration.

Users can choose from a wide variety of measuring instruments to suit their needs and field of application. For example, the latest development from the house of Rotronic, the Station 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. Measurement range: 0.00…1.00 Aw (0…100 %RH), -40…85 °C (-40…85 °F).

The high-end laboratory device, the HygroLab C1, for water activity measurements with up to four probes is ideal for measurement of water activity in cheese, meat, tobacco, animal feed and building materials. Equipped with an Ethernet or USB port for network capability, the benchtop device delivers reliable measured values within five minutes with its AW Quick function and the validated HW4 software supplied with the instrument guarantees complete programming and data logging possibilities. The station probes are designed for use with HygroLab C1 or HygroPalm HP23-AW-A. Minimised internal volume of the sensor chamber ensures fast equilibrium with all products. Range of application -40…85 °C (-40…185 °F) / 0…100 %RH.

The portable, mobile version for measurement of water activity is the handheld HygroPalm23-AW-A. Like the laboratory device, this instrument can also be used together with measuring probes and insertion probes. Range of application -10…60 °C (14…140 °F) / 0…1 Aw / 0…100 %RH.
