Moisture & Carbon Monoxide Visual Indicator

The 585 visual indicator allow an operator to see a moisture indicator card in the high pressure line. The cards are seen through a high strength plastic window. The moisture card is divided into sections which progressively change color from blue to pink as moisture increases. Other color changing indicators include a carbon monoxide indicator.
