Decagon Water Activity Meter: AquaLab Series 4TE
The AquaLab Series 4TE water activity meter has internal temperature control which allows you to choose a measuring temperature between 15 and 50°C. Since water activity is temperature dependent, the AquaLab Series 4TE will allow you to expertly manage the internal temperature to precisely measure the water activity of your product.

The AquaLab Series 4 can be used in:

  • Accelerated shelf-life studies.
  • Isotherm studies.
  • Studies determining the effects of temperature on a sample aw.
  • Evaluate the effects on a sample when there are large fluctuations in ambient temperature.
  • Meeting government or company regulations on temperature-specific aw measurements.

    Measure Water Activity and Moisture Content Simultaneously
    Decagon's new AquaLab DUO makes it possible to measure water activity and moisture content simultaneously with unmatched repeatability.

    To measure moisture content using water activity requires an understanding of the relationship between the two parameters. This relationship, referred to as the moisture sorption isotherm, is complex and unique to each product type. It must be determined experimentally by measuring water content at several water activity values. Decagon's AquaSorp isotherm generator can rapidly generate robust isotherms with unmatched data resolution. Once the isotherm has been generated, it can be loaded into the AquaLab DUO and used to indirectly determine moisture content based on a water activity measurement generated by the AquaLab DUO.

    Decagon Water Activity Meter: AquaLab Series 4TEV

    NEW Bench-Top Water Activity Meter for Measuring Volatiles such as Propylene Glycol and Ethanol

    The Series 4TEVe is designed specifically for measuring formulations that include volatiles such as propylene glycol and ethanol. The dual sensor block uses both a chilled-mirror dewpoint sensor and a capacitance sensor for measuring non-volatile and volatile substances.


    Decagon AquaLab Water Activity Meter: Series 3

    The AquaLab Series 3 is Decagon’s standard lab-grade water activity meter. The chilled-mirror dewpoint sensor offers unparalleled accuracy (±0.003aw) and extremely rapid read-time (<5min, including equilibration time).

    Leading food and pharmaceutical companies around the world rely on the AquaLab Series 3 and Series 3TE, as do small food companies, university labs, government facilities, pet food manufacturers, and many others. The Series 3 comes with a 3-year parts/labor warranty (the best in the industry).

    Reasons for using the Series 3:

    • Measurement of samples that have little change in aw with temp.
    • Measurement in a relatively temperature stable environment
    • Superior speed and accuracy.
