  • Dip a stick into the coolant fluid, then compare the resulting color change to the hardness (ppm) value color chart printed on the bottle label. Results are visible in just 3 seconds, making routine monitoring fast and straightforward.

  • The sticks measure calcium and magnesium concentrations in coolant across a range of 0 to 1,000 ppm. Tracking these levels lets you monitor the overall chemical condition of the coolant in a sump and catch changes before they affect performance.

  • One bottle of 50 sticks is designed to last approximately one year when used for a single sump. If you are monitoring multiple sumps, plan on using one bottle per sump annually.

  • No additional equipment or reagents are needed. The reference color chart is printed directly on the bottle label, so you can compare your result immediately after dipping — no meters, drops, or separate tools required.
