1. 【USE】: With this refractometer, the concentration of ethylene glycol and propylene glycol in the antifreeze of your car, solar system, heat pumps, the freezing point of windshield washer fluid, heating system, or other machines or systems can be determined.
2. 【MEASUREMENT RANGE】: Ethanediol (ethylene glycol): -500°C to 0°C; Propanediol (propylene glycol): -500°C to 0°C; Windshield washer fluid - ethanol + water: -40°C to 0°C; Propylene glycol + water (SRF1): -40°C to 0°C.Urea concentration 30% - 35%, battery acid 1.10 to 1.40 kg/L.【TEMPERATURE COMPENSATION】: Temperature compensation device included to ensure easy and convenient measurement. PRECISION MEASUREMENT: Adjust the optical system of the eyepiece group: 4-8x magnification system, continuous manual focusing. Can be adapted to all eye sizes.
4.【HIGH QUALITY: Our chrome-plated brass body is resistant to chemical corrosion and wear, increasing the refractometer's lifespan several times compared to other aluminum housings. Note: The data is measured manually; please allow for a 1-35cm error. Due to differences in lighting and screen settings, there may be some color variation; the actual product received shall prevail.
