The Pavlovsk State Museum in St. Petersburg required a monitoring system to track temperature and humidity without damaging the 18th century buildings. Testo installed probes and converters to monitor over 600 meters without interfering with the structures. They used wireless powerline communication through floors and basements to transfer data despite thick walls. The flexible testo Saveris system now precisely records conditions to preserve the museum's irreplaceable artifacts and heritage buildings.
