With the development of science and the advancement of production technology, the quantitative analysis of moisture has been listed as one of the basic items in the physical and chemical analysis of various substances. A moisture analyzer is an instrument capable of detecting the moisture content in various organic and inorganic solid, liquid and gas samples. As an important instrument for determining the water content of various substances, it is increasingly used in fields such as pharmaceuticals, chemicals, grain, soil, building materials and metallurgy.
In practice, moisture analysis methods can generally be divided into two categories: physical analysis and chemical analysis. At present, the main moisture analyzers on the market include Karl Fischer moisture analyzers, infrared moisture analyzers, dew point moisture analyzers, microwave moisture analyzers and coulometric moisture analyzers. These instruments are favored by many users in the instrument market for their simple operation, high sensitivity and good reproducibility, and their ability to perform continuous measurement with automatic data display.
Water has an important impact on food quality, and the importance of moisture analyzers as indispensable instruments in the food testing industry is self-evident. In recent years in particular, water-injected meat incidents have been prominent, posing a great threat to human health. To ensure citizens can eat "safe meat", food and drug regulatory authorities have actively taken measures to crack down on water-injected pork, beef and mutton. As a dedicated instrument for moisture content testing, the VicoMeter VM-E series rapid halogen moisture analyzer offers a fast and convenient testing process. Compared with the traditional standard loss-on-drying method for meat moisture testing, it completes a test in just 1 minute, and is therefore increasingly used to detect water injection in food.
In addition, moisture analyzers are equally indispensable in bread, cakes, fruits and vegetables. Moisture in food is the foundation for microbial survival, and microbial growth and reproduction is a major factor in food spoilage. By controlling the water activity in food, product quality can be improved and shelf life extended. A moisture analyzer measures the moisture content in food, reflecting the effective moisture of food in equilibrium, thereby indicating food stability and the likelihood of microbial reproduction, achieving the goal of food safety testing. At present, the VicoMeter VM-E series rapid halogen moisture analyzer is widely used in the food industry thanks to its compact size, uniform heating, fast testing speed, convenient operation and accurate results.
Through continuous development and innovation, China's product technology upgrades and category expansion are accelerating, and rapid moisture analyzers have entered a period of rapid development in the industry, earning praise from users across various fields. It is understood that traditional moisture analyzers have limited moisture measurement ranges and cannot cover both high and low moisture segments. Rapid moisture analyzers have broken through this bottleneck. At the same time, rapid moisture analyzers also adopt the water molecule polarization principle, enabling non-destructive measurement of the target.
Moisture determination can be used for control analysis in industrial production, for moisture testing of industrial and agricultural products, and even for moisture analysis in the laboratory with just a few microliters of sample solution. In the chemical field, moisture analyzers hold a solid position thanks to their fast and convenient measurement methods and reliable measurement data.
The chemical raw material moisture meter is a high-performance digital moisture measurement instrument launched domestically with imported advanced sensors. The instrument adopts the high-frequency principle with digital display, and the sensor is integrated with the main unit. It has multiple gears for measuring the moisture of various alkali-active dyes, chemical mineral raw materials, organic and inorganic chemical raw materials, dyes, resins, laundry detergent, metal soaps, auxiliaries and solutions in powder, granular and liquid forms. With advantages such as a wide measurement range, high accuracy, clear display, rapid measurement, stable performance and reliable indicators, and thanks to its small size, light weight and portability for fast on-site testing, it has become an ideal instrument for moisture testing of products in the chemical industry.
In addition, the battery industry is paying increasing attention to moisture in battery materials, especially battery separators. Because the separator density is very low, moisture testing poses certain difficulties, and many manufacturers have no good way to accurately detect the moisture content of separators. The development and use of moisture analyzers has solved this problem: moisture analyzers can detect separator moisture, preventing direct contact between the positive and negative plates that would cause a short circuit, while electrons migrate between the positive and negative electrodes through the external circuit to form a current for use by electrical equipment.
Product stability and measurement performance are important properties of an instrument. In the chemical industry, the rapid moisture analyzer holds a unique advantage in performance thanks to its uniform feeding function. Specifically, it delivers stable test results with good repeatability, enables tracking measurement, is easy to operate, and measures a wide variety of samples, providing a solid foundation for moisture measurement across various fields. It is worth mentioning that in today's era of environmental protection and energy saving, the rapid moisture analyzer also has the advantage of low energy consumption, with an operating current of less than 0.1 mA, greatly saving user costs and delivering a better experience.
As times advance, humidity and moisture measurement and control technology continues to develop. In recent years, foreign manufacturers of humidity and moisture analyzers have entered China one after another and captured market share. Although foreign moisture analyzers have certain advantages in accuracy and stability, they are expensive. In view of this, many domestic instrument manufacturers have strengthened their research and practice on moisture analyzers in recent years, achieving very significant results.
VicoMeter is a manufacturer specializing in the production and R&D of electronic testing instruments. For many years, the company has focused on the production and R&D of various electronic testing instruments such as rapid moisture analyzers. To date, it has built a complete range of testing instruments and equipment sold everywhere, widely used in scientific research and production units to assist with measurement, weighing and counting. The company's VM-E series moisture analyzers meet the requirements of automated instrument testing. At the same time, the products can effectively hold samples and improve test efficiency, and feature a maximum heating temperature of 250℃ and 2,000 valid storage addresses to meet the test result needs of different samples.
As a domestic provider of analytical instruments and testing equipment, VicoMeter also holds a pivotal position in the field of moisture determination. The company's infrared rapid moisture analyzers, halogen rapid moisture analyzers, meat moisture analyzers, trace moisture analyzers, Karl Fischer moisture analyzers, grain moisture analyzers, portable moisture analyzers and online moisture analyzers incorporate multiple inventions and new technologies, providing a reliable technical guarantee for the company's sustainable development. At the same time, with cutting-edge scientific research technology, product quality and dedicated service, VicoMeter has won the trust of many customers to meet the ever-changing challenges in the field of analytical instruments.
In summary, as an indispensable instrument for detecting moisture content in the testing industry, moisture analyzers will enjoy broader development prospects and applications. In line with current development trends, the moisture determination industry needs to continue attracting talent and devote itself to industrial development in the future. At the same time, instrument manufacturers should seize opportunities and continue to develop and produce faster and more convenient moisture analyzers, fully supporting all sectors of the industry toward better and more comprehensive development.
