HP23-AW-A Handheld Water Activity Kit

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. The HP23-AW-A is perfect as a portable analyzer with two sensor station inputs.
It includes many of the advanced features of the HygroLab C1, but in a convenient portable configuration.

• 2 input channels for HC2 sensor heads or HP2 insertion probes.
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, °C/°F, date and time
• Battery charging function

There are two types of sensors that can be used. Sensor heads (model HC2AW) comprise a puck shaped head which contains the electronics and ERH sensor (Equilibrium Relative Humidity). The sensor station is placed over a sample cup holder so as to form a sealed environment around the sample. The ensuing relative humidity in this sealed environment is the basis of water activity measurement. The sample is typically placed in a disposable sample cup which sits inside the sample cup holder.

The HP23 can also monitor the output from insertion probes. Insertion probes work in certain kinds of bulk products such as grain. When the probe tip is buried in the bulk material the local environment in the region of the tip is effectively isolated from the atmosphere and a local ERH can be obtained as if it were in a sealed chamber.
