HC2-AW Water Activity Probes
For water activity measurement of bulk materials, pastas, liquids, and solid pasty products
Rotronic HC2-AW water activity probes are designed to measure water activity in bulk materials, pastas, liquids, and other products.
HC2-AW water activity probes are available with either a digital UART output signal for use with Rotronic indicators such as the HygroLab C1 or the HP23-AW-A or with a USB output signal which plugs directly to the USB port of a PC running the HW4 software (Professional Edition with AwQuick, version 3.0.1 or higher) and is designed strictly for PC-based measurements. Multiple probes can be attached to a single PC.
Rotronic HC2 water activity probes are available as either standalone units or as parts of Sets:
