The Development Trend of Colorimeter

With the development of science and technology and the progress of precision instrument manufacturing, the performance of colorimeter is also constantly optimized and improved. A caliber 4mm pocket colorimeter is an instrument that decomposes light with complex components into spectral lines. Its measurement range includes the ultraviolet light region with a wavelength of 200-380 nm and the visible light region with a wavelength of 380-780 nm. colorimeter has the advantages of high sensitivity, wide application range, high accuracy, compact structure, low price, simple operation, less sampling, and superior anti-interference performance, so it has been widely used. By applying a colorimeter, qualitative analysis and quantitative analysis of the sample can be carried out. Quantitative analysis is to measure the concentration of a substance in a solution, and qualitative analysis is to characterize the substance according to the measured peaks of absorbed light at different wavelengths. Different light sources have their own unique emission spectra, so different luminous bodies can be used as the light source of the colorimeter. Among them, the light emitted by the tungsten lamp in the wavelength range of 380~780 nm can be refracted by the prism to obtain a red-orange-yellow light. The continuous spectrum of green, blue, indigo, and violet can be used as a light source for colorimeters.

Portable Spectrophotometer Colorimeter

A colorimeter is a kind of precise electrochemical analysis equipment, which has the characteristics of high precision, low detection limit, and low price. It can perform quantitative measurement, kinetic test, direct measurement of OD value, spectral scanning, multi-wavelength testing and food safety testing, Total phosphorus and total argon detection, heavy metal detection, DNA-protein detection, pesticide residue detection, etc. Therefore, the colorimeter has been widely used in the fields of the daily chemical industry, food manufacturing, beverage manufacturing, paper making, printing, ceramics, chemical industry, textile printing and laboratory. It can be seen that the colorimeter has a good application prospect and a large market demand.

At present, the more common colorimeters mainly include violet colorimeters, infrared colorimeters, fluorescence colorimeters, and atomic absorption colorimeters. From the perspective of the components of the colorimeter, the machine-etched grating is rapidly being replaced by the holographic grating; from the perspective of the configuration of the colorimeter, the microprocessor-controlled colorimetergradually replaces the manual single-beam, double-beam automatic colorimeters in the recording configuration; emerging colorimeters such as dual-wavelength colorimeters, fast-scanning colorimeters, etc. are developing rapidly. Under the background of today’s information socialization and social informatization era, realize the organic combination of colorimeter with computer technology, information technology, intelligent technology, and other emerging technologies, improve the intelligence level and automation degree of colorimeter, and ensure the photometric The meter can maintain the best working state and prevent the occurrence of human operation errors so that the accuracy and reliability of the test results of the colorimeter can be significantly improved. At this stage, improving the intelligence level and automation degree of the colorimeter is the main development direction of the colorimeter.

Pocket Colorimeter

It can be seen that the colorimeter is a physical and chemical analysis instrument integrating electronic technology, compact machinery, and optical technology, and has a broad development space. In practical applications, the colorimeter will be affected by errors in wavelength accuracy, baseline flatness, etc. Therefore, the maintenance and maintenance of the colorimeter should be strengthened in the daily use process to ensure the functionality of the colorimeter. can be fully utilized.
