There are many types of moisture analyzers. Below we will compare the two types of analyzers, so that we can draw the similarities and differences between the two different types of moisture analyzers.
The similarities between infrared moisture analyzer and halogen moisture analyzer:
The working principles of infrared and halogen moisture analyzers all use heating weight loss method, that is, work by external heating. First evaporate the moisture of the sample, and then obtain the moisture percentage of the sample through the electronic balance on the front of the heater. The accuracy of the moisture analyzer mainly depends on the accuracy of the electronic balance. At present, the accuracy of the conventional electronic balance is basically 0.001g.
The difference between infrared moisture analyzer and halogen moisture analyzer:
Halogen moisture analyzer is a new type of rapid moisture detection instrument. Its ring-shaped halogen heater ensures that the sample can be heated evenly during the high-temperature test, so that the sample surface is not easily damaged, and it quickly reaches dryness. During the drying process, the moisture meter continuously measures and instantly displays the moisture content% of the sample lost. After the drying process is completed, the final measured moisture content value is locked and displayed.
The difference is that during the heating process of the infrared moisture analyzer, due to the heating method of the infrared lamp, the temperature in the local area is relatively high, which is relatively easy to cause some areas to be superheated, while some areas may not be dry, resulting in uneven heating. At the same time, the infrared heating of the product will cause chemical changes to its interior, which also limits the development of infrared moisture analyzers.

DHS-16A Infrared Moisture Analyzer
Scope of application
DHS16-A multi-function infrared moisture meter is based on the structure of electronic balance, dissolved in heating unit. Under the control of a single-chip microcomputer, it is designed with electromagnetic force balance and infrared heating technology. This moisture meter is small in size, perfect in function, easy to use, and durable. There are many functions such as weighing calibration, temperature, time setting, manual and automatic heating selection, adjustable display parameters, etc., and with RS232 serial printer or computer, it can output 8 kinds of parameters, and four output modes are selected. Therefore, the moisture meter is widely used in laboratories and daily purchases and process control in the pharmaceutical, food, tobacco, food, chemical and other industries.

Halogen Moisture Analyzer:
Halogen rapid moisture analyzer is a new type of rapid moisture detection instrument. Its ring-shaped halogen heater ensures that the sample is evenly heated during the high-temperature test, making the sample table [1] surface [1] less susceptible to damage and rapid drying. During the drying process, the moisture meter continuously measures and instantly displays the moisture lost by the sample After the drying procedure is completed, the final measured moisture content value is locked and displayed. Compared with the international oven heating method, the test results have good consistency and are replaceable, and the detection efficiency is much higher than the oven method. General samples can be measured in just a few minutes. The instrument is simple to operate and accurate to test. The display part uses a red digital tube, and the display value is clearly visible. It can display data such as moisture value, sample initial value, final value, measurement time, temperature initial value, final value and so on. And has the function of connecting with computer and printer. The moisture meter can be widely used in all industries that need to quickly determine moisture, such as medicine, plastics, chemicals, food (surimi, dehydrated vegetables, meat and aquatic processing, noodles, flour, biscuits, moon cakes, etc.), food, feed, It has been produced and experimented in the fields of seed, rapeseed, tobacco, tea and textile, agriculture and forestry, papermaking, rubber, textile and other industries.
