What To Look For In A Portable Metal Detector

Article Written By: AnnTriune

Like a regular metal detectors, a portable metal detector is made to find metal objects. However, the portable one is designed specifically for more personalized use such as searching for metal or weapons carried by people, clothes, bags, or other objects.

Portable metal detectors have sensitive surfaces and special shapes that make them easier to operate, move around, and transport. Their uses vary from detecting metal, live wires, or wood stud location at home, which is ideal for most home owners. They can also be used as body scanners in business areas.

There are two types of portable metal detectors. There are hand held devices and walk-through metal detectors. Hand held metal detectors are light and easy to carry, with a small pouch or a wrist strap. Walk-through metal detectors come in small bags. They are foldable and easy to set-up and can be functional 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

When the metal detector battery is running low, the indicator light will flash to alert you. Metal detectors with rechargeable batteries usually take four to six hours to recharge. Normally, portable metal detectors consume less power with each use. You do not need to charge too often.

Note that not all metal detectors not designed to detect metal implants or objects inside the body. Furthermore, they cannot locate the exact location of the metal in the body. More sensitive metal detectors are 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.

To make sure the portable metal detector you choose works properly and is nt defective, check that it conforms to the international standards applicable for electrical safety, EC regulations, and EMC.

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.
