You should always check for pipes by hand, many pipes are PVC and will not show up on a metal detector.
Only if the mercury is in large concentrated amounts.
The Hand Held Meter Detector will work with all metals, although some may prove to be more troublesome than others.
The Hand Held Meter Detector will work on batteries, as long as you connect each lead to the battery correctly.

Check to see if it appears burnt or internal metal strip broken Test with a continuity tester (ohm meter)
No gold is non magnetic, but electromagnetism using a metal detector can. New designs differentiate ferrous metals like iron from nonmagnetic metals like gold, brass and copper.This known as ferro magnetism and dia magnetism. The detector has a meter or headphone signal to tell one from another.
It is normally measured with a carbon monoxide detector meter, concentration given in parts per million
depends on the density and metal content.
With a voltage detector or a multi meter. Don't touch the wires to your tongue. That would be bad!
yes
You can check glow plugs with an ohm meter. should be <1ohm
Purchase, borrow, or have someone with a volt meter or multimeter check it for you. If you don't know what a volt meter or multi meter is, have an electrician check it for you.
