Features You Need In A Portable Metal Detector
Ann Triune
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.
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.
A metal detector is not designed to locate or pinpoint the location of metal objects or implants inside the body. There are other devices made to do that instead.
Portable metal detectors have indicator lights and sounds to alert you of its status. If the indicator light is green, this means the device is switched on. If it is amber, this means the battery is low, and you will need to recharge before it dies. If the light is red, this means it has detected metal. Some metal detectors vibrate or sound off. A metal detector cannot determine if an object is magnetic or not, though.
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 operator does not need specialized training to use the device. It can be used for personal reasons such as fixing your home or searching for lost things, or for business reasons. These include uses in places that require tight security such as airports, banks, bars, businesses, courtrooms, malls, schools, and other public areas.
