The Digital TENS/EMS is a battery operated pulse generator that sends electrical impulses through electrodes into the body to reach the nerves and underlying muscle groups. This unit is a combination stimulator of TENS and EMS which can be used for muscle stimulation and/or pain relief. The device features four controllable output channels, each independent of each other. An electrode pair can be connected to each output channel. The intensity level is controlled by the press of buttons corresponding to each output channel.
