Reichert Duo-Chek Engine Coolant and Battery Tester Refractometer
Manufacturer: Reichert Family Part
#: REICHERT TSI-1375
Reichert Duo-Chek Engine Coolant/Battery Tester (refractometer) now featuring an all black, polymer housing, which is impact resistant, water proof, and improves image quality. Also featuring a blue prism for improved scale and reading visibility. Accuracy in testing engine coolant is important to ensure adequate freeze and boil-over protection. Accurate coolant concentration also means the viscosity and heat transfer properties are correct. The proper coolant/water mix provides proper cooling system operation and prevents engine damage from cavitation corrosion. The Duo-Chek measures both Ethylene Glycol and Propylene Glycol based engine fluids. (Propylene Glycol is the environmentally-friendly antifreeze, which hydrometers cannot measure.) The Duo-Chek is available in two models, the DC60 which measures in °C and the DC70 which measures in °F.
