Concentration Control:
To ensure optimal performance and tool life:
- Use a handheld refractometer to measure fluid concentration.
- Multiply the refractometer reading by the Refractive Index Factor (1.25) to determine the concentration.
- Adjust concentration as needed:
-
- Add water to reduce concentration.
- Add product concentrate to increase concentration.
