When applied to bobs and other gauging devices, these toothpaste-like mixtures turn colors to determine the level of gas or water – depending on the product chosen – in a tank. Formulated for the petroleum industry, they also have some petrochemical applications. For best shelf life, store between 50 – 85 °F / 10 – 29 °C.
We perfected these two products for McCabe and Sons of Danville, Vermont and manufacture them in our facility.
