The Amrex MS324AB Low Volt AC Muscle Stimulator (#01-MS324AB) is intended for low volt AC muscle stimulation. Both the MS324A and MS324AB are dual-channel, four-pad, low voltage electrical muscle stimulators that produce pulsation, tetanize, surge, and reciprocal output.

Note: This unit is for professional use only, and is for sale by or on the order of a practitioner only. Prescription required for patients.

Warranty: 2 Years (Generator) - Parts and Labor.

The MS324AB and MS324A possess a unique patient treatment stop switch. The treatment stop switch allows the patient to halt stimulator output instantly with the press of a button. This fosters more confidence through patient control and creates a more comfortable environment to have that option available.

For portability, or when ac plug-in power is unavailable, the MS324AB also contains an internal rechargeable battery power supply for reliable power. It can also be wall mounted for convenience in the treatment room.

This device is also typically combined with Amrex ultrasound devices for well-rounded combination therapy treatments. Low voltage electrical muscle stimulation may be applied separately or it may be combined with therapeutic ultrasound simultaneously through the ultrasound transducer of a SynchroSonic U/50.
