4-in-1 Refractometer, Antifreeze Glycol Measurement, Water Disc Freezing Point Measurement, AdBlue Concentration Measurement, Battery Acid Measurement

This versatile refractometer allows for precise analysis of the condition of automotive and industrial fluids. It measures the freezing point of ethylene glycol and propylene glycol between -50°C and 0°C. The device also checks the AdBlue concentration and battery acid density from 1.10 to 1.40 kg/l. Thanks to automatic temperature compensation, measurements remain reliable. This essential tool helps maintain your vehicles and heating systems without unnecessary replacements. Material: Plastic and optical glass. Measuring range: Ethylene glycol: -50°C to 0°C. Measuring range: Propylene glycol: -50°C to 0°C. Measuring range: Water from glass: -40°C to 0°C. Measuring range: AdBlue: 30% to 35%. Measuring range: Battery acid: 1.10 to 1.40 kg/l. Optical system: 4x to 8x magnification. Compensation: Automatic Temperature Compensation (ATC). Package weight: Not specified. Package dimensions: Not specified. Technical specifications: This refractometer covers four scales including ethylene glycol and propylene glycol from -50°C to 0°C, water from glass from -40°C to 0°C, AdBlue from 30% to 35% and battery acid from 1.10 to 1.40 kg/l with optical magnification of 4x to 8x. Compatibility and accessories: Ideal for cars, solar panels, and heat pumps, the kit includes two pipettes, a calibration screwdriver, a cleaning cloth, and a hard case for secure storage. Installation and use: Manually adjust the eyepiece for a clear view without glasses, apply the liquid to the prism, and read the value directly thanks to the integrated automatic temperature compensation. Other information: The package contains a detailed user manual to guide you through each measurement step, ensuring quick analysis of antifreeze and battery condition before winter. Precautions for use: Measured values may vary slightly depending on ambient lighting or prism cleanliness; it is recommended to clean the surface after each use to ensure accuracy.
