xxxxx:

• monitor contaminants to inhibit corrosion and prevent microbial growth
• measure pH to maintain metal solubility and fluid stability
• provide system flushing and filtration procedures to improve new fluid performance
• help prevent serious health risks and environmental issues that poorly maintained metalworking fluids can create

Testing concentration and pH on a daily basis – or at least three times a week – monitors corrosion, metal solubility and emulsion stability. Acids, biocides and dirt can be monitored on a weekly basis but should results change, daily testing should be done until the cause has been identified and levels return to normal.
