1.功能来划分：
1. Function to divide:
1）全金属检测仪：可以检测到铁、不锈钢、铜、铝等所有金属。检测精度和灵敏度都比较高，稳定可靠。
1) All-metal detector: can detect iron, stainless steel, copper, aluminum and other metals. The detection accuracy and sensitivity are relatively high, stable and reliable.
2）铁金属检测仪：只能检测到铁质金属，俗称检针机。检测精度和灵敏度较低，容易干扰。
2) Iron metal detector: only iron metal can be detected, commonly known as needle detector. The detection accuracy and sensitivity are low and easy to interfere.
3）铝箔金属检测仪：也仅能检测到铁质金属，但是检测带铝箔包装的产品时，其检测精度和灵敏度仍然较高。
3) Aluminum foil metal detector: Only iron metal can be detected, but the detection accuracy and sensitivity of products packaged with aluminum foil are still high.
2. 按用途来划分：
2. By use:
1）手持金属检测仪：
1) Handheld metal detector:
A.最早应用于机场，车间，码头，传扬，场馆的公共安检，
A. First used in airports, workshops, wharfs, propaganda, public security venues,
B.工业上主要用于防止企业含量有金属万分的产品流失，
B. In industry, it is mainly used to prevent the loss of products containing ten thousand metals in enterprises.
C.最近几年在中国市场也应用在各种考试当要，防止考生作弊。比如高考，研究生考试，公务员考试等。
C. In recent years, the Chinese market should also be applied to all kinds of examinations to prevent cheating. For example, college entrance examination, postgraduate examination, civil service examination and so on.
2）地下金属检测仪：
2) Underground metal detector:
A.最早应用在军事中的扫雷，
A. Mine clearance, first used in military affairs,
B.考古中探测文物，探险中的探宝。
B. Exploring cultural relics in Archaeology and treasures in exploration.
C.现在地下金属检测仪主要用于金属材料的探测，目前全国拥有一支使用地下金属检测仪探测，挖掘废旧金属的探测大军。
C. At present, underground metal detectors are mainly used to detect metal materials. At present, the whole country has a large army of detectors that use underground metal detectors to detect and excavate scrap metals.
