The application of water based paints requires the precise control of the environment in which they are applied. Reliable sensors are a pre-requisite for this process.

Application: Paint manufacturers run accelerated trials on the paints stability in various conditions, humidity being a key factor. 
Environmental chambers are primarily used, but also exposure to outdoor weathering conditions (hence Met Probe usage)
