Grass Technologies SD9 DUAL SQUARE PULSE STIMULATOR
For Nerve and Muscle Stimulation
for student teaching as well as research laboratories.
The built-in isolation circuit enhances subject safety and minimizes stimulus artifacts.
The twin pulse circuit makes this stimulator ideal for refractory measurements.
0.02 to 200 msec (4 decades); Separates PREPULSE SYNC OUT pulse from the stimulus pulse; Used to set refractory time interval for TWIN PULSE operation
PREPULSE SYNC OUT precedes the stimulus pulse as selected by the variable delay; PULSE SYNC OUT occurs at the end of delay period which is coincident with the onset of the stimulus pulse
Built-in to allow recording with the stimulator at the preparation site with minimum artifact; Output voltage not referred to ground; Output polarity selectable
Can be selected to reduce electrode polarization and ion transfer
Flashes with each stimulus pulse
10% or better for all parameters
30 watts at 110 volts, 50/60 Hz; Typical Power is 5 watts
9.5" W x 5.25" H x 5.5" D (24.1 cm x 13.3 cm x 14 cm)
Safety: UL 3101-1, CSA C22.2 No. 1010-1, EN 61010-1 Other European Standards: EN 55011, EN 50082-1 European Directives: 73/23/EEC, 89/336/EEC

Item Powers up and appears to be working properly.
These unit is from a local university hospital
and came from a working environment.
