Various types of moisture analyzers

At present, the market's rapid moisture analyzer mainly includes Karl Fischer moisture analyzer, infrared moisture meter, halogen moisture meter, dew point moisture meter, microwave moisture meter, Coulomb moisture meter, and some special moisture meters. These instruments are simple, sensitive, and reproducible. They can measure continuously and automatically display data. The Karl Fischer method is a classical method. After improvements in recent years, it has greatly improved the accuracy and expanded the measurement range. It has been listed as a standard method for moisture determination in many substances. The dew-point moisture analyzer is easy to operate, the instrument is not complicated, and the measured results are generally satisfactory. It is often used for the determination of trace moisture in permanent gas. However, this method interferes more. Some cold-changeable gases, especially at higher concentrations, interfere with condensation than water vapor. Coulomb moisture meters are often used to determine the moisture content of gases. This method is easy to operate, quick to respond, and especially suitable for the determination of trace moisture in gases. If you use ordinary chemical methods, it is very difficult. However, electrolytic methods are not suitable for the determination of alkaline substances or conjugated diolefins. The microwave moisture analyzer uses the microwave field to dry the sample. The milliporesdi accelerates the drying process. It has the characteristics of short measurement time, convenient operation, high accuracy and wide application range. It is suitable for grain, paper, wood, textile and chemical products, etc. The determination of moisture in powder, solid and viscous solid samples can also be applied to the determination of moisture in petroleum, kerosene and other liquid samples.

The infrared moisture analyzer is simple in operation, less time-consuming, and accurate in measurement results. Therefore, the infrared moisture meter can be widely used in laboratory analysis, daily stock control, and process detection in chemical, pharmaceutical, food, tobacco, food, and other industries. Called the old generation of classic fast moisture analyzers, but the infrared heating process, due to the infrared lamp heating method, resulting in the focus point, the local area temperature is high, it is easy to cause partial heating and superheat, resulting in a paste, and part The area may not be dry. Relatively speaking, heating is not uniform. At the same time, as the product heats the infrared, it will produce chemical changes inside it, which also limits the development of the infrared moisture analyzer. The latest technology, the HWLSC50 Halogen Moisture Analyzer, removes the shortcomings of infrared moisture analyzers, heats evenly, quickly increases the temperature, and quickly gains market acceptance. Its circular halogen heater ensures that the sample is even during the high temperature test process. When heated, the surface of the sample is not easily damaged and dried quickly. During the drying process, the moisture analyzer continuously measures and instantly displays the lost moisture content of the sample. After the drying process is completed, the final measured moisture content is locked and displayed, and its technical performance is The indicators are leading in China. The HWLSC50 Fast Moisture Analyzer provides a fast, simple moisture measurement process with accurate, reliable measurement performance and the ability to measure moisture levels as low as 0.001. By optimizing drying and conditioning processes, users can save time and effort.

Infrared and halogen moisture analyzers are based on the same principle, they are heating weight loss method, that is, external heating, evaporation sample moisture, and then through the heater on the front of the electronic balance to obtain the percentage of moisture in the sample, fast moisture analyzer The accuracy depends mainly on the accuracy of the electronic balance. The accuracy of current conventional electronic balances is basically 0.001g (thousandths of a thousandth). The accuracy of the HWLSC50 halogen fast moisture analyzer electronic balance is 0.0001g (one ten-thousandth) is a new type of rapid moisture detection instrument. The simple moisture meter display of the Sartorius MA35 Infrared Moisture Analyzer displays all important information at a glance. The simple and easy-to-understand symbol of the MA35 infrared moisture meter guides you to complete the measurement in 3 steps (measured from the pimple). Without affecting the flexibility of use and measurement accuracy, we optimized the program options of the MA35 infrared moisture analyzer, making its operation very simple and practical.

Compared with the international oven heating method, the test results have good consistency, are replaceable, and the detection efficiency is much higher than the oven method. General samples take only a few minutes to complete the measurement. The instrument is simple in operation, accurate in testing, and the display part adopts a red digital tube. The indication value is clearly visible, and the data such as the moisture value, the initial value, the final value, the measurement time, the initial temperature value and the final value can be displayed respectively. And has a connection with the computer, printer. The moisture meter can be widely used in all industries that need to measure moisture quickly, such as plastics, rubber, chemicals, medicine, food, and other industries during the production and experiment process.
