McCabe H20 Plus+ Water Level Indicator 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.

Use 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. Thereafter, the dark purple color change lightens to a fuchsia/light purple change in a 50% water/50% alcohol bottom. When the water/alcohol bottom reaches approximately 75% alcohol, the color change is a light green up to 99% or more alcohol (mainly an alcohol bottom).

Total water percentage readings in E-10 gasoline only.

The color will change based on the water/alcohol concentration.

PLEASE NOTE: You can also do an outage gauge/top gauge to see if ethanol is suspended in your RFG. The dark green paste will bleach or lighten when it comes in contact with RFG. The paste will not change color when in contact with gasoline.
