    AWTherm – Water Activity Meter

    AWTherm Stabilized Temperature Water Activity Meter

    Stable temperature yields precise measurements.
    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 wide control range permits measurements to be integrated directly in the tempered manufacturing or storage process. Water-activity measurement reacts very sensitively to variances in temperature. Stabilizing the temperature prevents imprecise results due to external temperature influences.

    Exchangeable measuring head
    A further advantage of AwTherm is that the measuring head is removable, which means that the probe can be temperature-calibrated or adjusted to give high precision.

    User-friendliness
    The AwTherm shows its paces in island-operation mode, with its simple handling and clarity. No laboratory should be without the device in conjunction with the ROTRONIC HW4 software

    Why measure water activity?
    The free water in a product influences its microbiological, chemical and enzymatic stability. If there is too much free water present, the products spoil; too little water can be detrimental to the product characteristics.

    Water activity Contaminants
    aw = 0.91..0.95 Many bacteria
    aw = 0.88 Many yeasts
    aw = 0.80 Many mildews
    aw = 0.75 Halophile bacteria
    aw = 0.70 Osmiophile yeasts
    aw = 0.65 Xerophile mildew

    Measuring water activity provides useful information about characteristics such as cohesion, storage lifetime, clotting or pourability of powders, tablets, etc., or the adhesive properties of coatings.

    Handheld Portable Water Activity Meter HP23-AW-A

    Portable Water Activity Meter HP23-AW-A

    It is very useful to measure water activity in production or storage rooms, e.g. inspection of bulk materials to ensure they meet specifications. The HygroPalm HP23-AW-A offers the perfect solution for on-site water activity measurements to confirm product stability and indicate shelf life, but also suitable as a mobile laboratory unit. Equal to the HygroLab C1 the HP23-AW-A is perfect as a portable analyzer with two probe inputs for any suitable HC2 probe. It can also be used in conjunction with HW4-P-QUICK-Vx for 4-5 min readings.

    This handheld instrument is specially configured to suit the water activity user. 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.

    Portable Water Activity Meter Features 

    • 2 input channels for HC2 station probes or HC2 insertion probes can be connected for measurement of water activity, relative humidity and temperature
    • AW Water activity Quick function for fast measurement results (typically 4-5 minutes)
    • Audible alarm to indicate completed measurement
    • Saves up to 10'000 data records with %rh, °C, date and time
    • Battery charging function
