Portable Precision Water Activity Meter


Water activity meter with portability needed? Then our LabSwift is the perfect device for you. With a rechargeable battery as an option, this meter can be placed and used anywhere.

It is particularly useful for products in powder form or dried fruits with low to medium aw-values, because this meter does not exhibit a temperature stabilisation in its measuring chamber.

Advantages:

 

  • Optional use of a rechargeable battery for portability
  • SD-card for simple data management
  • Reusable SAL-T verification standards
  • Fast meter for medium aw value range
