McCabe H2O Water Indicating Paste

McCabe H20 Plus+ Water Level Indicator is a dark green paste that turns dark purple when it comes into contact with water. It can detect free water in almost all petroleum products as well as some petrochemicals. It has a toothpaste-like consistency.

To Use:

Spread a smooth, even layer of the paste on the bob or gauging device where you anticipate free water to be present. Lower the gauging device through the petroleum product to the bottom of the tank and leave it for approximately five seconds or more. Heavier products may require a longer immersion time. If there is water present, the green paste will turn dark purple. When reading the results, please note a straight demarcation on the gauging device.

se in reformulated Gasoline (RFG):

McCabe H20 Plus+ can also be used to determine the presence of water and water/alcohol bottoms in RFG. There are gradient color changes as one moves through different levels of water/alcohol concentrations. The normal dark purple color change seen when gauging just water bottoms is also seen in water/alcohol bottoms where the bottoms range from 0% to 35% alcohol. Th
