MAXEMS 2000 digital unit, dual channel. The MAXEMS 2000 is a battery operated pulse generator that sends electrical impulses through electrodes to the body and reaches the underlying muscle group. The device is provided with two controllable output channels, each independent of each other. An electrode pair can be connected to each output channel. The electrodes of the MAXEMS 2000 create electrical impulses whose amplitude, pulse rate, contraction time, relaxation time and ramp time may be altered with switches. Dial controls (Press buttons) are very easy to use and slide cover prevents accidental changes in the setting. Includes: (1) Analog EMS Unit, (4) Electrodes, (2) Leadwires, (1) 9 Volt Battery, (1) Carrying Case and Instruction Manual.
