What to Look for in a Portable Metal Detector
A portable metal detector is used to search for metal, weapons, or contraband, possibly carried by people or stowed in bags, objects, or clothes. In principle, they work the same way as any other metal detector.
These types of metal detectors have sensitive surfaces and special shapes that make them easier to operate. These can be used at home to detect metal, live wires, or wood stud location. They can also be used as body scanners.
There are two types of portable metal detectors-hand held devices and walk-through. The hand held metal detectors are easy to carry, since most of them come with a bag, a pouch, or a wrist band. They are also lightweight. The walk-through metal detectors can be folded and carried around in a small bag. They are also easy to set-up and can be used within five minutes.
A list of the technical features in a portable metal detector includes the following:
- 9V battery power supply - Adjustable sensitivity - Battery life in continuous operation is maximum of 50 hours with NiMH batteries, and 150 hours with alkaline batteries - Built-in buzzer with high-intensity pulsed acoustic alarm - Indicator lamps for power on, alarm, and low battery charge - Operating temperature of 5 to 140 degrees Fahrenheit (-15 to 60 degrees Celsius) - Relative humidity at 0 to 95 percent - Shock-resistant - Three-position switch with visible or with audible and visible alarms - Vibration function to enable silent work - Weighs 1 lb (0.4 kg), more or less
For models with rechargeable batteries, charging time will usually take four to six hours. An indicator light will flash to alert you if the battery is running low or when the voltage is insufficient. Portable metal detectors have low power consumption, so you will not have to recharge too often.
Not all models of portable metal detector can find or pinpoint the exact location of metal implants or objects in the body. There are more sensitive devices made for that purpose.
Indicator lights glow either green, amber, or red. Green light means the device is on, amber means low battery, and red light is for alarm. Some models flash red and emit a sound at the same time. However, the metal detector cannot determine if the object is magnetic or non-magnetic.
Check that the portable metal detector conforms to the international standards applicable for electrical safety, EC regulations, and EMC. This will make sure that the device has been tested to work properly and is guaranteed to be free of defects. If something does go wrong with the metal detector, it will be easier to replace.
A portable metal detector can be of personal or business use, so operators do not need special training. They are not meant to invade privacy, but to ensure safety and protection in security-sensitive places such as airports, banks, bars, businesses, courtrooms, malls, schools, and other public areas.
