    Chemical-Level Indicators

    Check the level of liquids containing chemicals such as alcohol-based solvents, boric acid, and sodium bicarbonate. These indicators can be used in pressurized applications where overflow is a concern. All have an aluminum gauge shield that protects the glass window from impact. Clear liquids magnify a red line at the back of the window, so their levels are easier to see.
