Grass Technolgy S88X Dual Output Square Pulse Stimulator
The S88X is a dual output, general purpose stimulator for nerve and muscle stimulation procedures.
This new stimulator has touch-pad controls.
Applications extend from single cell to entire muscle stimulation. The two output channels can be operated independently or synchronized to produce complex paradigms. The outputs are non-isolated constant voltage monophasic, biphasic or twin pulses. Up to 9 sets of parameters can be saved for future use.
New features include:
• Digital controls – precise timing accuracy
• Bright display simplifies setup
• Independent or synchronous channel operation
• Monophasic and biphasic modes
• Dual train output
• High current output facilitates field stimulation
• New companion isolation units
• Software replacement via USB cable
