WATER ACTIVITY What is equilibrium relative humidity? Equilibrium relative humidity (ERH) is the value of relative humidity into which a hygroscopic product can be placed where no net exchange of moisture between the product and the surrounding environment can take place. It is expressed on a scale of 0…100 %. ERH is typically used in the paper and pharmaceutical industries, but can be applied to almost any product that is sensitive to moisture, or where the presence of moisture can affect product handling. Aw or ERH? Both Aw and ERH are an expression of the amount of free water vapor...

Aw Accessories Sample holders and sample containers The sample holders provide excellent sample containment and optimum temperature stability. The WP-40TH can be attached to a water bath for additional temperature control. The disposable sample containers ensure the optimum sample volume is introduced into the sample holders. They prevent the sample holders from coming into direct contact with the product being tested, thereby preventing soiling or cross contamination. The sample containers also provide a convenient means of collecting and storing samples. Packaging unit Order code Clamp...
