The invention relates to an industrial three-phase isolation ampere meter. An A-phase sampling resistor (1) is connected with a single chip microcomputer (7) after a sampling signal is amplified by an A-phase differential amplifier (4); a B-phase sampling resistor (2) is connected with the single chip microcomputer (7) after a sampling signal is amplified by a B-phase differential amplifier (6); a C-phase sampling resistor (3) is connected with the single chip microcomputer (7) after a sampling signal is amplified by a C-phase differential amplifier (3); after acquired data is subjected to analog-digital conversion by the single chip microcomputer (7), current is displayed by an LED (Light Emitting Diode) digital display (8) in real time; meanwhile, the current is output to an interface circuit (10) by an optoelectronic isolation module (9) and is used for the collection of other auto control instruments.
