 The compass, also known as the compass, is a tool used to indicate directions, and it is widely applied in various fields of direction judgment, such as navigation, field exploration, and reading urban road maps. The compass is divided into two types: one that relies on magnetic force and one that does not. The first type can be further divided into two categories: one is the geomagnetic compass, which is made based on the polarity of the Earth's magnetic field, but this compass indicates the direction of the north and south differently from the true north and south, with a magnetic declination; the other is the electronic compass, which uses the magnetic resistance (MR) technology of the magnetic field sensor to well correct the problem of magnetic declination, and it has now been widely used in GPS positioning devices. As for the one that does not rely on magnetic force, it purely relies on the internal physical methods of the device to indicate the direction, such as the compass car or the inertial navigation system. British sinologist Joseph Needham called the compass one of the "four great inventions of ancient China." In some places, such as Taiwan, the compass is called the north-pointing needle, because the contemporary pointing needle is often painted with a color mark at the end pointing to the north, which is convenient for users to find the north.This factory specializes in the production of compasses.Please provide the Chinese text you want to translate, and I will translate it into English for you.Temperature Gauge ManufacturerPlease provide the Chinese text you want to translate, and I will translate it into English for you.The main varieties include::outer diameter9.6mmand12mmand14mmand15mmand16mmand18mmand20mmand22mmand25mmand27mmand30mmand35mmand40mmand45mmand63mmand70mmThe circular pointer and dial-style compass;28mmand38mmCar-mounted compass ball; outer diameter15and18and20and25and30and35Circular thermometer; plastic and metal compass mountaineering buckle; Muslim prayer compass; scale map compass; compass keychain";Multifunctional Compass Whistle; Multifunctional Metal Compass.
