AMREX MS324A Low Volt AC Muscle Stimulators

Reliable, Affordable and Portable Muscle Stimulation

MS324A, MS324AB Low Volt AC Stimulators
The MS324 and MS324AB are designed for the pplication of low volt ac muscle stimulation. The MS324A an MS324AB ar dual hannel, four pad. low volta e electrical muscle stimulators th t produce pulsation. tetanize, surge, nd reciprocal output.

Tl1e MS324A and MS324AB feature the p tient treatment top switch Designed to promote patient assurance, the treatment stop switch allows the pat,en to discontinue st1 ulator output at the press of a button.

For portability, or when ac power is unavailable. the MS324AB utilizes an internal rechargeable b ttery power supply.

MS322 Low Volt AC Muscle Stimulator
The MS322 Low Volt AC Muscle S imulator combines proven reliability and ac power in a compact low volt ac muscle stimulator. The MS322 is a single channel, two pad, low voltage electrical muscle stimulato1 that produces pulsation tet nize an surge output.

Combination Therapy
The MS324A, MS324AB and MS322 may be used for combination therapy. Low voltage electrical muscle stimulation inay be pplied se arately or 11 may be combine w1 h therapeutic ultrasound simultaneous ly through the ultrasound transducer of an Amrex SynchroSoni U/50.
