Overview
Enviro Test Construct Water pH Meter indicates the free water content when food is stable and measures the possibility of microbial proliferation. Food formulators use water activity to predict how much moisture migration will affect their product so that to choose suitable package and storage methods to reduce the usage of antiseptics.
Features
- Chip inside sensor
- The measured object is unlimited, liquid solids and powder etc.
- Printer output, could store data for a long time
- Chemical resistant
