Hand Refractometer is specifically designed as an analog instrument. This is widely used for determining liquid’s refractive index. Basically, the device works on the principle of critical angle in which lenses and prism project a shadow line on the glass which is installed inside the instrument. There are varieties of scales present on it, which easily measure the dissolved solids in solution. Thus, this has become the most admired device used in different sectors related to wine making. We are presenting Hand Refractometer to our clients in different model.
