Document/Video Guide

Monitor coolant chemical condition with these hardness testing sticks. Why rely on your coolant guy to keep your coolant in its top chemical condition when it is so easy to do yourself, and prevent coolant problems?

  • Easy-to-use: Dip into fluid and compare your color reading to hardness (ppm) value color chart on bottle label
  • Results in 3 seconds
  • Range of 0-1000 ppm calcium and magnesium
  • 50 sticks per bottle
  • One bottle lasts a year per sump

Minerals in tap water adversely affect the chemical nature of the coolant emulsion. Each coolant works within a specific range of hardness so it is important to check the initial water supply for its hardness level. Then monitor each sump weekly, as evaporation leads to a build up of minerals – like scale on plumbing, which can cause problems.

When hardness level is too high, concentrate breaks from oil/water emulsion and floats on the fluid surface. It gets skimmed off like oil and can easily plug particle filters.
The rest is mostly water, providing insufficient lubrication and causes broken or prematurely worn tooling.
Rust preventative may be required since the natural lubricant of coolant is no longer part of the fluid pool. Machine interiors may also become affected.
Grease may form as chips interact with the concentrate. Grease is not easily skimmed and can plug filters.
Lack of minerals cause foam, which prevent oil skimming as the surface tension changes. Foam also encourages tank overflow.
