HHTEC 3-in-1 Refractometer Antifreeze Tester with ATC, Coolant Battery Washer Fluid Tester, Ethylene Glycol Propylene Glycol Car Battery Acid Measuring Tool

• 3-in-1 automotive liquid tester: Designed to test coolant antifreeze, battery acid and washer fluid. Ideal for quick checks of multiple vehicle liquids with one tool.
• Wide measurement ranges for common fluids: Measures ethylene glycol, propylene glycol and battery fluid density, helping determine freezing point and condition of automotive liquids.
• Fast and accurate reading with ATC: Equipped with automatic temperature compensation (ATC) for reliable readings. Simply place a few drops on the prism and read the result instantly.
• Easy to use with clear scale: Apply 2–3 drops of liquid, close the cover plate and read through the eyepiece. No complicated setup required.
• Not suitable for alcohol or sugary liquids: This refractometer is not designed for alcohol, wine, beer or sugar-based liquids, as these require different measurement principles and scales.

Technical details: The models have only one unit system: °C. By indicating the percentage we can see the freezing point of ethylene glycol or propylene glycol-based cooling systems. It can also be used to test the concentration of ethylene glycol or propylene glycol in antifreeze fluids. The RHA-200ATC features an automatic temperature compensation system. This precision instrument has high quality optics with extremely even focusing. It features an overall precision optical system design, five groups of optical lenses made of high-quality materials and chrome-plated film processing, a light transmission rate of more than 94%. You can use the refractometer in weak light and read accurately. Specifications: Ethylene glycol: -60°C - 0°C, 0 - 66.6% vol. Propylene glycol: -50°C - 0°C, 0 - 62.4% vol. Battery liquids: 1100 - 1400sg. Dimensions: 20 x 7.5 x 5.5 cm. Accessories: 4 pipettes, cleaning cloth, screwdriver and portable bag. -
