The IM 2220 is a portable instrument, easy to use for measuring the impedance of the constant voltage speaker lines or of a single loudspeaker.
The test range is quite wide thanks to the three measure fields (20 Ohm, 200 Ohm, 2000 Ohm). It is suitable for both commercial audio and domestic use. The IM 2220 is easy to use, comfortable and safe, thanks to the large control knob, to the large display and the high insulation.
