1, the equipment's own capabilities. Now on the market metal detector analog and digital machines, digital machines and digital single-frequency detection and digital dual-frequency detection. Digital dual-frequency simultaneous detection only Japan Anritsu one, high sensitivity, good stability.
2, the size of the equipment detection port. Metal detector channel the smaller the high sensitivity.
3, the product's own characteristics. The shape of the product, weight, packaging materials, temperature, salt, moisture and so on. All of these determine the size of the effect of the product, the effect of large sensitivity is poor.
4, with the equipment related to the surrounding environment. Such as vibration, peripheral equipment, power supply.
Two, all metals can be detected, just the size.
