Problems solved by technology

[0003] At present, hand-held refractometers are widely used in the market and in factories and mines. They can be read with the naked eye through the eyepiece. Due to the fact that manual reading errors are unavoidable and can only be measured by sampling, the efficiency is low and the Abbe number cannot be measured; while the refractometer used in the laboratory Digital refractometers, like traditional visual methods, are subject to sampling limitations and cannot meet the needs of on-site continuous and real-time measurements; high-precision digital refractometers are affected by the optical path and have a large volume

Embodiment Construction

[0025] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0026] Combined with the manual Figure 1-6 The probe-type digital display refractometer includes a host 1 and a probe 7. The host 1 is divided into upper and lower layers. The upper layer inside the host 1 is the optical signal sending side, and the lower layer inside the host 1 is the optical signal receiving side. The optical signal sending side includes a signal processing circuit board 10 and a laser light source control circuit board 11, which are electrically connected between the signal processing circuit board 10 and the laser light source control circuit board 11, and are provided at the exit of the upper layer optical fiber interface 6 inside the ho...

Abstract

The invention relates to a probe type digital display refractometer, comprising a main machine (1) and a probe (7); the probe type digital display refractometer is characterized in that the main machine (1) is internally divided into an upper layer and a lower layer; the upper layer in the main machine (1) is an optical signal sending side, and the lower layer in the main machine (1) is an opticalsignal receiving side; an optical fiber interface (6) is formed in one side wall of the main machine (1); an optical fiber connector (9) is connected with the optical fiber interface (6); the opticalfiber connector (9) is connected with the probe (7) by means of an optical fiber (8); a display screen (2), an on-off key (3), an adjusting key (4) and a locking key (5) are separately arranged on the upper surface of the main machine (1). The probe type digital display refractometer overcomes the influence of visual reading errors in the prior art and realizes the real-time online measurement ofrefractive indexes within a certain range; non-sampling measurement is realized in the environment where the probe can intervene, and the size of the probe is greatly reduced by means of optical pathdesign; therefore, the probe type digital display refractometer is suitable for applications such as oil measurement and sugar measurement.

Description

technical field [0001] The invention relates to a refractometer, in particular to a probe-type online digital refractometer, which belongs to the field of liquid concentration and refractive index measuring devices. Background technique [0002] Refractive index is one of the important physical constants of matter. The refractive index is closely related to the concentration of the solution. Many pure substances have a certain refractive index. If there are impurities in them, the refractive index will change and there will be deviations. The more impurities, the greater the deviation . Therefore, by measuring the refractive index, the purity of a substance can be determined. Abbe refractometer (also known as Abbe refractometer) is an instrument designed according to the principle of total reflection of light. It uses the method of measuring the critical angle of total reflection to measure the refractive index of unknown substances, and can quantitatively analyze certain c...
