|OELCHECK test instrument:||Mettler-Toledo pH/Ion bench meter SC S220-B|
|Sample quantity:||25 ml|
|Test result:||pH value|
|Brief description:|| |
The pH value indicates the basic or acid character of a solution or rather is a measure for the strength of a basic or acid effect of a solution.
It is divided as follows:
The pH value is a fundamental value for aqueous medias. For coolants, it is essential for the corrosion tendency. The higher the pH value the more likely a coolant attacks an aluminum component.Since different degradation products lower the pH value of a coolant, a decreasing value also indicates the end of a coolant's operating time.
