Specification Brand : ZNNRKMYO BulletPoint1 : Handheld portable refractometers are convenient for users to conduct on-site measurements at different locations, such as collecting water samples and testing agricultural products when going out. BulletPoint2 : Refractometer products are usually made of sturdy and durable materials that can withstand a certain degree of collision and wear, adapt to different working environments, and ensure long-term stable use. BulletPoint3 : The refractometer has automatic temperature compensation function. Because the refractive index of liquids changes with temperature, this function ensures accurate measurement in different temperature environments without the need for manual temperature correction, improving the convenience and accuracy of measurement. BulletPoint4 : No complicated operations are required. Simply place the sample on the prism and press the button (digital model) to read the results within seconds. Clear dual scale display and automatic calibration ensure easy operation for both beginners and professionals. BulletPoint5 : This refractometer can meet diverse needs and is an ideal choice for home brewers, gardening enthusiasts, and educators.
