A glycol refractometer is an essential measuring instrument for assessing the concentration of antifreeze and battery fluids in solar systems, heating systems, and other technical applications. Our handheld refractometer REF412 provides a practical solution with three scales for precise measurements.

The first two scales display the freezing point of the tested liquid in °C, allowing for accurate verification of antifreeze concentration. This ensures that your solar systems and heating systems are effectively protected against frost damage.

The third scale measures the specific gravity of battery fluids, enabling users to determine the charge status of lead-acid batteries commonly found in cars, motorcycles, and boats. With the REF412 glycol refractometer, you can maintain optimal performance and safety in all your systems.
