Abstract
The invention provides a handheld concentration refractometer which comprises a prism table, a detection prism, a cover plate, a retaining screw, a regulating screw, a lens barrel, a lens barrel outer-sleeve, a diopter regulation hand wheel and an eyepiece. The lens barrel is arranged inside the lens barrel outer-sleeve, and the surface of one side of the lens barrel is fixedly provided with the regulating screw. The lens barrel and the prism table are fixedly connected through the retaining screw. One side of the prism table is tightly connected to the cover plate, and the detection prism is arranged between the cover plate and the prism table. The handheld concentration refractometer has a compact structure, is fast, accurate and light, and is small in size. Calibration is simple and easy to implement when distilled water or corrector plate is used for calibration. The device is simple to operate, and is stable and durable in use. Measurement is fast and efficient, and work efficiency can be raised effectively. After simple treatment, a sample can be directly put on the detection prism to start detection. The handheld concentration refractometer has good economic benefit and social benefits and is suitable for popularization and application.
