As a mobile laboratory unit, the Rotronic HygroPalm HP23-AW-A is perfect for on-site water activity measurements to determine the stability and preservability of the sample being analysed. It is ideal for measuring water activity in production processes such as random checks of cheese, meat, tobacco, building materials, animal feeds, bakery products, paper, medicines, horticulture, agriculture, and more.
Benefits
- 1 s, 10 s, 1 min, 10 min measurement intervals
- 2 input channels for HC2 station probes or HC2 insertion probes can be connected for measurement of water activity, relative humidity and temperature
- AW Quick function for fast measurement results (typically 4-5 minutes)
- Audible alarm to indicate completed measurement
- Saves up to 10'000 data records with %rh, ℃, date and time
- Battery charging function
Training for the Rotronic water activity meters is available for an additional cost. Please contact us for more information on pricing and availability.
