CAS DataLoggers recently provided a real-time versatile monitoring solution for a museum housing fragile paintings and other artwork which needed to be protected against excessive illumination and ultraviolet light. Both these threats could fade or change the color of paint and dyes, so the building needed to make sure their UV light filters and tinted panels were fully effective. Excessive temperature and humidity levels could also irreparably damage the museum’s collection. Existing installations and pieces in transport all required a compact, lightweight solution to record all the necessary parameters including temperature, humidity, wide-range illuminance, and UV light levels. The museum searched for a wireless real-time monitoring and alarming device which could ensure that all these parameters were closely controlled.
