Reichert Duo-Chek 70 (DC70)
The Duo-Chek® Engine Coolant/Battery Tester (refractometer) from Reichert offers a fast and easy-to-use method for testing engine coolant freeze point and battery charge condition. It provides automatic temperature compensation for immediate, accurate direct readings of ethylene glycol or propylene glycol coolants or deicing fluids. The Duo-Chek is avakable in two models: Model DC70 (Cat. No. 137584L0) measures freeze point protection in degrees Fahrenheit and Model DC60 (Cat. No. 137564L0) measures in degrees Celsius. NOTE: Accuracy of the refractometer readings can be affected by the specific coolant formulation of the individual manufacturer.
