A low-resistance ohmmeter such as the Robin KMP3050DL.

to ensure a SAFE earth a mutimeter is useless
Standards vary (but they all relate to this)
Not only should the resistance be below 0.5 Ohms
it should be able to withstand 25 Amps
So the test is 25 Amps and less than 12 Volts
(Meter)
Continuity / Bonding / Safety Earth tester
all replies so far read are wrong (especiallty the one that mentioned MegOhms lol / sigh)

There are two tests for earthing:
Dead Earth Test, which tests safety earthing systems.
Potential Gradient Test, which tests the quality of signal earths.
The standard tester for this is the Earth Tester No. 3.
It can be hired from most electronic hire centres. Try Livingstone Hire, or Computer Lease.

Soil resistances vary greatly but most will be in the megohm ranges. So when you go to purchase a multimeter or ohm meter, ask for one that has several high megohm ranges. You shouldn't have to pay more that $20 to $40 for one from any decent supply house. Radio shack used to have one for $22 dollars that went to 200 megohms. Happy Testing!

A metre is a measure of distance, a multimeter measures
resistance, voltage ampage etc!

An ohm meter.
But in fact any multimeter will have Ohms on it.
[Ohms is resistance]
