In many situations it can be very useful to measure water activity in production or storage rooms, e.g. inspection of bulk materials to ensure they meet specifications. The HygroPalm 23-AW-A 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, etc.
Applications
The HygroPalm HP23-AW-A offers the perfect solution for on-site water activity measurements to confirm product stability and indicate shelf life. The HP23-AW-A is suitable as a mobile laboratory unit. Equal to the HygroLab C1 the HP23-AW-A is perfect as a portable analyzer with two probe inputs for any suitable HC2 probe. The HP23-AW-A can also be used in conjunction with HW4-P-QUICK-Vx.
Portable and convenient
Handheld instrument specially configured to suit the water activity user. It includes many of the advanced features of the HygroLab C1, but in a convenient portable configuration.medicines, horticulture, agriculture, etc.
