1 box each EA35 (35 %RH) and EA80 (80%RH) humidity calibration standards
Carrying case
The HygroPalm AW1 is a battery operated water activity indicator with a single probe input and features three operating modes:
AwQuick: accelerated water activity measurement with automatic end of measurement
AwE: conventional water activity measurement with automatic detection of equilibrium and automatic end of measurement
Standard: water activity and temperature measurement, limited to just indicating the values and the trend of the values
The HygroPalm AW1 is compatible with all the models of HygroClip probes to permit the direct measurement of products in bulk and quality control of packaging materials.
The probes used with the HygroPalm AW1 indicator can be calibrated and adjusted at one or more points, directly from the instrument keypad. Reference humidity values are provided by using the ROTRONIC certified humidity standards.
A docking station is available for table top use. When used with an external AC adapter, this allows powering the instrument without draining the battery. Battery charging is possible with the appropriate type of battery.

Water activity (aw) is one of the most critical factors in determining quality and safety of the goods you consume every day. Water activity affects the shelf life, safety, texture, flavor, and smell of foods. It is also important to the stability of pharmaceuticals and cosmetics. While temperature, pH and several other factors can influence if and how fast organisms will grow in a product, water activity may be the most important factor in controlling spoilage. Most bacteria, for example, do not grow at water activities below 0.91, and most molds cease to grow at water activities below 0.80. By measuring water activity, it is possible to predict which microorganisms will and will not be potential sources of spoilage. Water activity--not water content--determines the lower limit of available water for microbial growth. In addition to influencing microbial spoilage, water activity can play a significant role in determining the activity of enzymes and vitamins in foods and can have a major impact their color, taste, and aroma. It can also significantly impact the potency and consistency of pharmaceuticals.
