The metal detector can be used in food, pharmaceutical, chemical, textile, clothing, toy paper, hygiene products, electronics, recycling industry, etc. It is suitable for detecting broken needles, wire, and metals mixed or left together with products and raw materials. The use of metal detectors can help relevant companies to pass HACCP, GMP, FDA, QS, and ISO9001 certifications. Next, we take a look at the important role of the Food metal detector. Here are some answers.

The metal detector is the most important tool for archaeologists in the field.
The metal detector is increasingly being used to assist surface penetrating radar and other ground-penetrating radar systems.
The metal detector not only detects arms but also coins, lock picks, and other metal objects. In field archaeology, most of the evidence is metal, such as musket cartridges, cartridges, bullets, cannon and artillery shells, grenades, and swords, depending on the historical period in which the battle took place. Therefore, the most important tool for the field archaeologist is the simple metal detector.
For decades, the Belt metal detector was criticized for being taken for granted as a " weapon " for grave robbers. It was not until 1983 that Richard Fuchs and later Douglas F. Fox and later Douglas Scott proved through their analysis of the Little Big Horn battlefield that decades of painstaking archaeological work could be completed in a very short time through systematic metal detector surveys. They estimated that metal detectorists could only find perhaps 10 out of the 5,000 ancient artifacts excavated at the Little Big Horn battlefield by conventional means. Today, skilled metal detectorists work alongside archaeologists and conservators, who play a very important role in field archaeology, recording the precise location of finds and "encapsulating, labeling and marking" them. In other words, each ancient artifact was encapsulated, labeled, and placed in the hole cut when it was dug, so that its precise location could be identified and mapped before it could be removed for later study.
The conveyor metal detector is increasingly being used to assist surface penetrating radar and other ground-penetrating radar systems. The SPR system, originally developed in the UK to detect plastic mines, is capable of locating anomalous objects below 30 meters above the surface. The system also provides a range of clues to help users identify evidence that has not yet been excavated. But even locating a metallic artifact is only half the battle. In the mid-1990s, during the analysis of the Battle of Monmouth, American archaeologists discovered several musket cartridges with a mottled surface that had been crushed as thin as chewing gum. To determine the original dimensions, an archaeologist by the name of Dan Sivilich, an engineer by training, invented a formula that combined physics and chemistry to calculate the original diameter of any non-spherical musket slug. It was rightly called the Sivilich Formula and is now used daily in battlefield archaeology around the world. Once the original dimensions of a deformed or incomplete musket or gun slug have been estimated, ballisticians join in and begin calculating the range of the gun's fire. Today's metal detectors generally offer several special features developed by various manufacturers in addition to the basic detection and warning functions.
