The Hygrolab is a monitoring station for water activity sensors. It can monitor up to 4 channels and is supplied complete with software for data aquistion and manipulation. 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 has 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 Hygrolab 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.
