Digital WA-60A Food Water Activity Tester 

0.02 Precision Foods Water Activity Measurement

Applications:

Can be used to measure the water activity of foods. No matter when and where you need to 

measure water activity, WA-60A water activity meter is your unique choice.

The Water Activity, mainly reflects the amount of free water in the state of food balance, 

the stability of food and the possibility of microbial reproduction, and the 

chemical,enzyme and physical changes that can cause the change of food quality.

It is often used to measure the dryness enduring ability of the microorganisms. By measuring the water activity of food and selecting reasonable packing and storage methods,the use of 

preservatives can be reduced and the shelf life of food, grain and fruits andvegetables can 

be judged.

For example,when the water activity level is up to 0.91,then it is good for bacteria growth.

Bacteria >0.91

Yeast >0.88

Mould >0.70

Hypertonic yeast >0.60

No microbial growth <0.60
