Description

High-precision refractometer Technical Field The utility model relates to the technical field of refractometers, in particular to a high-precision refractometer. Background The refractometer is an instrument for measuring the concentration of liquid by utilizing light rays, and is used for measuring the refractive index, double refractive index and light property, wherein the refractive index of the liquid, the solute content in the solution, the sugar content of wine, the water content in high-sugar solution, the salinity of seawater, the specific gravity of battery electrolyte and the like, and is widely applied to the industries of petrochemical industry, light industry food, medicine and health, environmental protection greening and the like. When the conventional refractometer is used, the correction screw on the refractometer is used for zeroing, so that the detection accuracy is improved, and then the liquid sample is dripped into the measuring groove of the refractometer and is measured through the prism assembly and the like. For example, the utility model discloses a high-efficiency refractometer with the publication number of CN210803258U, which comprises a prism seat, a refractive prism arranged on the prism seat, and a light inlet plate hinged on the prism seat and positioned above the refractive prism, wherein a liquid feeder is detachably connected to a refractometer body, the liquid feeder comprises a mounting frame which is slidably arranged on the prism seat, a flexible liquid inlet pipe arranged in the middle of the mounting frame and a force application piece which is arranged on the mounting frame and used for extruding the liquid inlet pipe, and a liquid outlet of the liquid inlet pipe faces the refractive prism after the mounting frame is arranged on the prism seat.
