LabSwift-aw Water Activity Meter
Water activity instrument with local flexibility
Suitable for products such as powder or dried fruit with low to medium aW values, as the measuring instrument does not have temperature stabilization of the measuring chamber.
All data of a measurement, including the desired protocols, are stored on a SD card and can be transferred to a PC or printer.
Data is provided in Excel format, allowing you to easily analyze the information. This assures the full quality assurance and traceability of all measurement data. Optional software is available (extra cost) for advanced data analysis.
The large LCD with intuitive menu structure displays water activity (Aw), temperature and stability. The meters uses the latest non-contact infrared sampling technology and a maintenance-free Aw sensor. Use the optional filters (extra cost) to accurately measure samples with critical additives such as alcohol, acids, bases and chlorine.
The unique Aw sensor is designed to be field-calibrated after multiple uses. The reusable standards, if kept closed in the supplied airtight container, can last several years, saving on overall operating costs. The sensor can also be easily replaced when it is no longer performing to factory specifications - it is the sensor which holds all of the factory-calibrated values within it, allowing the unit to be within calibration.
- Accurate, reproducible, fast aw-value determination
- Highest reliability and long term stability
- Easy menu structure and clear display
- Ergonomic housing design
