Handling Instructions

CHALLENGE 300-HT is designed for use at economical dilution ratios and is equally effective in hard and soft water. Maintaining dilution ratios with a hand-held refractometer is recommended. A pH meter is also useful. Develop production-specific scales by obtaining accurately measured samples of a properly diluted mixture that corresponds to use. Maintain a higher concentration for recirculating, filtered coolant systems.
