• Determination of causes for damage to ceiling fresco
• Ascertainment of relative humidity and temperature conditions on the fresco itself
• Complementary installation of laminar flow sensors to determine a potential connection
• between soiling and room air circulation.

• Measurement of the surface temperature and –moisture on the ceiling fresco without impairment of the still existent colour ground
• Measurement of the air current on the ceiling cornices
• No changes to existing structures by the measurement facility
• Ensure recording of measurements in 10 minute intervals even during evening current shut down
