Digital Glycerin-Chek Fahrenheit RefractometerWhy take chances? For precise reading of Glycerin coolant concentration, hydrometers just don't measure up. The Reichert Digital Glycerin-Chek accurately and effectively tests Glycerin coolant Freeze Point, Boiling Point, and % Concentration. This fast, simple test provides greater peace of mind for your customers while increasing your service business.Our accurate digital tester performs three critical tests on the engine coolant:Measures Freeze Point of Glycerin coolantMeasures Boiling Point of Glycerin coolantMeasures % ConcentrationFire Sprinkler Systems: Our tester can be used to measure the concentration of antifreeze formulation in wet fire sprinkler systems.Get dependable digital accuracy in a three-in-one tool!Our accurate digital tester performs three critical tests on the engine coolant:Measures Freeze Point of Glycerin coolant: The Reichert digital Glycerin-Chek's Automatic Temperature Compensation (ATC) provides immediate, accurate, and direct readings at ASTM D3321 standard of +/-1 degree F. This ensures that the coolant has a low feezing point, so there are no engine block or radiator freeze-ups when the vehicle is not in operation during the cold winter months.Measures Boiling Point of Glycerin coolant: The engine coolant raises the boiling point of water in a vehicle's cooling system. This guards against boil-overs, engine break-downs, and ensures that the cooling system is operation at peak efficiency.Measures % Concentration: Measures the exact concentration of the Glycerin and water mixture to ensure the engine coolant is at the correct chemical specification. Detect for either over-concentration or under-concentration of the coolant - either scenario will cause damage to engine components.
