Working Procedure of Automatic Moisture Analyzer




The main job of an automatic moisture analyzer is to know the moisture level of a substance by measuring the weight lost after being heated for a certain period of time. The majority of these instruments are capable of measuring the moisture level of any substance that has 0.1% to 99.9% moisture in it.

Before starting the actual measurement procedure, the laboratory technician must take samples of the slurry, solid or liquid he will test using a moisture analyzer. Next, the technician needs to set the drying parameters for the sample. Instruments used for measuring moisture levels will show results based on these parameters.

If you use this type of gauge for the first time, you should be aware of the fact that these tools work according to the principle of TGA or thermogravimetric testing. This is the same principle we mentioned at the beginning of this article; TGA tests help measure the weight lost by certain substances as a result of heating. The weight loss analysis caused by liquid evaporation can help in determining the moisture content of the substance.

If the device you use knows the parameters of drying certain substances, it will always keep those parameters in mind while heating the furnace. Drying parameters are usually determined by the chemical arrangement of the material; for example, if water is the main liquid thermogravimetric analyzer tga present in the material, its drying parameter is likely to be 105 ° Celsius.

After adjusting the device and setting the drying parameters, the laboratory technician must close the humidity analyzer. Closing the device before starting the actual measurement procedure is a must to get accurate results.

After the technician closes the instrument, the sample will start to heat up. This will continue for a certain period of time and all through this process the analyzer will continue to record the weight lost by the material. The process will last until the furnace is turned off. However, samples are not deleted from the device instantly. The technician allows her to sit for 5 to 10 minutes before removing it.

Are you wondering how you would know its size? This device produces prints of all recorded data each time they perform a humidity measurement job. Some of the information to be printed includes the sample's original weight, sample weight after being dried and the amount of moisture present in it.
