WaterWorks Propylene Glycol Check is said to be the world’s first visual test strip that measures propylene glycol levels. With simpler operations than a refractometer, the strip verifies that fluids are in good working order to prevent damage to cooling systems. The strips can test for levels in water from 20–60%. Test strips only need to be dipped in water for 2 s to conduct a check. After dipping the strip, users can determine the propylene glycol levels after just 60 s. The strip will change colors, indicating its status. The strip’s color is then matched to an included color chart. — Industrial Test Systems (ITS), Inc., Rock Hill, S.C.
