DESCRIPTION:
YW -681 series instruments are digital display high -precision optical instruments designed using the principle of refraction , which can be used to measure the sugar content of liquids , such as fruits and beverages.
The YW-681 series is designed with a protective cover. When measuring in a strong light environment, covering the protective cover can greatly reduce light interference. In addition, when measuring volatile solutions, covering the protective cover can avoid measurement errors caused by excessive volatilization of the solution.
The YW-681 series has a temperature compensation function, which can reduce the influence of temperature changes on the measurement results. The instrument also has waterproof protection function, the protection level is IP66, and can be directly washed with a small water flow. This series of instruments is compact and easy to carry.
