Application
Changes in the coolant quality can be detected by the self-monitoring function and corrected as necessary. Among other things, the pH value must be recorded here. Depending on the manufacturer's specifications, the pH value of the coolant should lie between 7.7 and 9.2 pH. This measurement must be made when preparing the concentrate, and once weekly for emulsions ready for use. Strongly decreasing pH values run the risk of corrosion, poor biostability combined with unsatisfactory downtimes (additional costs), unpleasant odours and health hazards. Measures must be taken in the event of a decrease in pH of 0.2 pH, and the coolant should be changed in the event of a decrease of 0.5 pH.

Execution

• Combination of °C and pH
• Fast, accurate, simple
• Reliable thanks to automatic final value detection
• Robust, insensitive to contamination
