The voltage/current measured by the electric meter, pointer meter and multimeter are inconsistent.
Phenomenon: During on-site debugging, such situations often occur: the same voltage and current are inconsistent when measured by different instruments, with deviations as small as 20~30 and as many as 60~70. So which is more accurate in measuring electricity meter, pointer meter or multimeter?

Add fluxing agent or active ingredient to the soda-lime jar
Because of its good chemical stability, bottle glass has no pollution to the contents; because of air tightness and high temperature resistance, a certain mechanical strength and reliable use; because of transparent or colorful and help to improve the grade of goods. Therefore, bottle glass is mainly used for product packaging in food, alcohol, beverage, medicine and other industries.

Features of magnetic voltage regulator
Due to the role of saturable reactor inside the magnetic adjustment, the reactor has a current limiting function, so it can obtain better external characteristics of falling, strong overload capacity, especially the ability to bear load short circuit is incomparable to other transformers.

Differences and similarities between borosilicate glass and tempered glass
Different types of specialty glass have unique properties that are required in different general situations. Borosilicate glass is a common glass in laboratory glassware, it is a very crack-resistant glass. Tempered glass is more common and can be seen in many places, such as safety glass doors and windows, which are treated to make them stronger and safer.

High borosilicate glass with stable internal structure
Because the high borosilicate glass has the characteristics of low expansion rate, high temperature resistance and high strength, the glass is calcined at 630 ℃. Therefore, it can use temperature changes and is not easy to break, so many companies now use this glass to produce products. High borosilicate glass compared with ordinary glass, the glass has what advantages? I believe a lot of friends are not very understanding of this, then, let Xiaobian simple to introduce to you, take a look at it!
