The EV-906 Digital 4-Channel TENS/EMS Unit is a battery operated as well as AC connect pulse generator that sends electrical impulses electrodes to the body and reach the nerves and underlying muscle group. This unit is a combination stimulator of TENS and EMS which can be used for muscle stimulation and pain relief. The device is provided with 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 press buttons.
The unit is ideal for clinical and daily homecare

Precise Intensity Control
There are 100 steps of intensity level controlled by press buttons from 1 to 100mA.
Press Button Control
The power, intensity level and parameter are controlled by press buttons, which is easy for the users to adjust the settings. All of the buttons are protected by a swing door to avoid accidental touch.
Large Liquid Crystal Display
A large LCD in 6.1 x 4.4 cm showing the intensity level, settings and treatment timer. The selected modes and parameters are readable.
Two Treatment Timers
There are two individual timers controlling the output of CH1, CH2 & CH3, CH4. This function is ideal when two patients accept treatment with the same machine.
Treatment Time Countdown
The output will shut off automatically when time is up.
Compliance Meter: The unit can store 60 sets of record of operation
