Tenma Digital Audio Speaker Impedance Tester

This Digital Audio Speaker Impedance Tester is essential for reliable installation of background music and paging systems in residences, office buildings and public areas. Avoid costly service calls and amplifier damage by verifying actual speaker system impedance prior to operation. Unlike conventional Volt/Ohm meters, which measure DC resistance, this unit utilizes an internal 1kHz oscillator to measure true impedance.
