This element is highly sensitive to moisture and will gradually change color in direct relation to an increase or decrease in the moisture content of the system. The "Dry-Caution-Wet" system operating conditions are then easily determined by matching the element color with the colors displayed on the reference label. Colors change as often as the system moisture content changes. The indicator will display a wet condition upon installation and may take several hours to acclimate to the system being installed in.
