Megger is used for measuring an insulation resistance of
motor winding of cable etc. which is measured in megaohm.
While earth tester has earth electrodes which are used to
measure eathpit resistance & it is measured in ohm.
megger is used for measuring insulation resistance in mega
ohm range ,while earth tester is used for measuring the
earth resistance which is always less than 5 ohms ie a low
resistance
