Manufacturers of pharmaceutical and chemical products are obliged to document their process and storage conditions. Moisture-Mapping-Validation is an inexpensive way to fulfil these requirements. According to the size of the space to be validated a defined number of moisture sensors and temperature sensors are operated for a defined period of time. For example, the application of 9 sensors for a period of 48 hours is recommended for a space of up to 2 m ³. As an accredited calibration laboratory we can supply certified staff and suitable measurement technology for the implementation of Humidity Mapping-Validation.
