What should be paid attention to when purchasing a moisture meter?

Moisture meter is also called moisture meter, moisture meter, fast moisture meter, moisture meter, moisture detector, moisture meter, moisture analyzer, moisture content detector, water meter, water tester, moisture meter. It can be widely used in all industries that require rapid moisture determination, such as medicine, plastics, chemicals, food (surimi, dehydrated vegetables, meat and aquatic product processing, noodles, flour, biscuits, moon cakes, etc.), grain, feed, seeds, vegetables Seeds, tea, textiles, agriculture, forestry, paper, rubber, textiles and other industries in the production and experiment process.

 

1. It is best to consider automatic instruments when choosing. The manual moisture analyzer requires the tester to visually inspect the reagent in the glass burette, and also needs to be manually closed after reaching the end point. The delay due to different action habits of each person will bring unnecessary errors.

 

2. When choosing, you should consider purchasing a fully enclosed test system. The naked Karl Fischer reagent is very easy to absorb water due to the presence of iodine, and the ethyl ester sample and methanol solvent to be tested should also try to avoid the situation that the water in the air dissolves and causes errors.

 

Third, the life of the metering pump should be considered. The metering pump is a key part of the volumetric moisture meter, and the Karl Fischer reagent is a highly corrosive reagent. You should try to choose a metering pump made of fluoroplastics and other corrosion-resistant materials to prevent leakage and cause the instrument to scrapped.

 

Fourth, the electrode problem. This part belongs to the core part of the instrument. On the one hand, it should have high sensitivity. On the other hand, because it is immersed in the test pool during the test, it is best to choose an instrument equipped with high-quality platinum electrodes to maintain the life of the electrodes.
