The pH value of the cooling water of grinding and drilling equipment should never rise above 9.5, otherwise skin burns and increased corrosion will result. With this indicator paper you can measure pH values in the range from 0 to 14.
Hold the litmus test strip in the cooling water. After approx. 15 seconds you can read the result and compare it with the pH colour chart. The test strip provides reliable results within seconds in the pH range between 0 and 14. The indicator strips are on a roll (4.8 m) and are simply peeled off in the desired size
Application note:
Our tip: with approx. 3 % Vetrocool coolant the pH value remains < 9.5
