Abstract

The invention discloses a universal online industrial refractormeter used for detecting the solution concentration. The refractormeter comprises an instrument shell, a control panel is arranged on one side wall of the instrument shell, and a solution concentration monitoring module is arranged inside the instrument shell, and is connected with the control panel. The invention also discloses a method for detecting the solution concentration by utilizing the universal online industrial refractormeter used for detecting the solution concentration, a solution monitoring module is used for acquiring the CCD optics and temperature signals of a to-be-detected solution, a data processing system in a main control panel of a single chip microcomputer is used for carrying out signal processing on the concentration value of the to-be-detected solution; the concentration value is sent to a standard industrial signal output module to be processed so as to obtain standard industrial signals which are used for carrying out the step that an instrument is used for regulating and controlling the production concentration for the second time; meanwhile, the solution temperature, refractive index and concentration value are obtained through detection and are displayed. The universal online industrial refractormeter used for solution detection has the characteristics of rapid measurement speed and high measurement precision.

Description

technical field [0001] The invention belongs to the technical field of solution detection instruments, and relates to a general-purpose online industrial refractometer for detecting solution concentration, and also relates to a method for detecting solution concentration by using the above-mentioned general-purpose online industrial refractometer. Background technique [0002] At present, most of the online refractometers produced at home and abroad can only measure the concentration of the solution as a whole; for multi-component solutions, they can only measure the total concentration of various solutes in the multi-component solution, but cannot measure The concentration of each solute in a multivariate solution. In addition, most of the existing on-line refractometers are used for sugar content measurement, which is the shortcoming of the current imported and domestic on-line refractometers. [0003] As we all know, concentration is an important index to measure many in...
