This type of instrument is hand-held portable needle detector, also known as hand-held needle detector, hand-held needle detector, hand-held metal detector, etc. Using the principle of magnetic field, it can effectively detect extremely small iron objects such as broken needles.
Scope of application: places where metal impurities need to be detected in clothing, buttons, zippers, textiles, shoe materials, hardware and chemical industries, assist large needle detector to accurately find the real parts of steel needle or ferromagnetic metal impurities in defective products, and can also be used to detect whether metal jewelry contains metal impurities prohibited by environmental protection certification such as iron, cobalt and nickel. Improve enterprise product quality.
The instrument can inspect ferromagnetic substances in drugs, food and chemical raw materials.
The instrument can check the existence of nails, steel bars and pipes in wood, walls and tables.
The instrument can also check the injury, knife injury, crush injury and other parts of human body and livestock, and check whether harmful iron filings and debris seep into it.
The instrument can also be used for the rapid search of hidden murder weapons and guns by the inspectors at the border guard post
Power supply: 6F22-9V power supply, static current less than 5mA, dynamic current less than 30mA, saving electrode consumption
Volume: 195mm (L) x58mm (W) x50mm (H)
Sensitivity: the diameter of 1.0mm iron ball can reach 10mm high. The highest sensitivity can detect an iron ball with a diameter of 0.8mm. The diameter is 0.7x20, and the broken needle can reach 50mm high.
Note: the instrument can work continuously for a long time without heating and overload. When the power supply voltage is lower than 6V, it will produce continuous beeping sound, which indicates that the power is insufficient and the battery of the same model should be replaced.
