Take Control of Your Coolant’s Health with Our Hardness Testing Sticks

 Why depend on your coolant provider to ensure your coolant is in prime chemical condition when you can do it yourself? With our Hardness Testing Sticks, you can easily prevent coolant issues before they arise. Commonly employed in industrial and manufacturing settings, these test strips are your go-to tool for reliable quality control and inspection.

Make the Smart Choice: Our Hardness Testing Sticks
  • Ease of Use: Simply dip into fluid and match your color reading with the hardness (ppm) value color chart on the bottle label.
  • Quick Results: Get accurate results within a remarkable 3 seconds.
  • Wide Range: Suitable for measuring 0-1000 ppm of calcium and magnesium.
  • Generous Quantity: Each bottle contains 50 sticks – enough for consistent testing.
  • Longevity: One bottle is enough to last a year per sump.

Be proactive, keep your coolant in top condition, and prevent potential problems with our Hardness Testing Sticks.

Remember, minerals in tap water can adversely affect the chemical nature of your coolant emulsion. As each coolant operates within a specific hardness range, it’s vital to check your initial water supply for its hardness level. Regular weekly monitoring of each sump is recommended, as evaporation can lead to a buildup of minerals, causing issues similar to plumbing scale.

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.
