What is Coolant?

Coolant, also known as antifreeze, is a liquid substance used in engines and industrial machinery to regulate temperature and prevent overheating. It circulates through the engine's cooling system, absorbing heat generated during operation and transferring it away from critical components. Coolant typically consists of a mixture of water and additives, such as ethylene glycol or propylene glycol, which lower the freezing point and raise the boiling point of the liquid. Additionally, coolant contains corrosion inhibitors to protect engine components from rust and corrosion. Proper coolant maintenance is essential for engine longevity and optimal performance, as it helps prevent freezing in cold temperatures, boiling in hot conditions, and corrosion within the cooling system.

Why Use a Coolant Refractometer?

• Accuracy: Coolant refractometers provide precise measurements of coolant concentration, ensuring optimal performance and protection.
• Prevention: Maintaining the correct coolant concentration prevents freezing in cold temperatures and boiling in hot conditions.
• Corrosion Protection: Proper coolant concentration helps prevent corrosion and rust formation within the cooling system.

How to Use a Coolant Refractometer

• Calibration: Ensure the refractometer is calibrated properly before use. Use a calibration fluid with a known refractive index specific to coolant measurement.

Sample Preparation

• Apply Sample: Place a few drops of the coolant sample onto the prism of the refractometer. Close the lid, if applicable, to spread the sample evenly.
• View and Read: Look through the eyepiece of the refractometer towards a light source. Take the reading where the boundary between light and dark areas intersects on the scale.
• Temperature Compensation: Some refractometers feature Automatic Temperature Compensation (ATC), which adjusts the reading based on the temperature of the coolant sample. Ensure the refractometer is set to the correct temperature range for accurate measurements.
• Cleaning and Maintenance: After each use, rinse the prism with distilled water and dry it with a soft cloth to prevent residue buildup. Store the refractometer in a protective case in a dry, cool place to maintain its accuracy and longevity.
