Moisture Indicator Disk
A moisture indicating disc for our visual indicators. This disc is designed to show the relative humidity in a progressive scale. As 20 percent relative humidity is reached, the pie shaped section marked “20” will change color to pink. The same for 40 and 60. Normally filters should be changed before a relative humidity of 60 is reached. Color will revert back to blue when a new filter is placed in the system.
