AMREX IF150 Interferential
This unit is a "True" Interferential with two channels and a four pad output. The IF 150 is microprocessor controlled for precise operation. Six pre-programmed beat frequency sweep ranges include settings for pain (80 to 150 Hz) edema (1 to 10 Hz.) and rehab (1 to 150 Hz.) along with much more. This is an excellent unit for the money.
