ACC-101 shown with ACC-PS1 power supply, and
BOS-200 oscilloscope, both sold separately.

The ACC101 accelerometer is
low cost yet extremely durable.
It is constructed of high-strength
aluminum; has a rugged strain
relief, a rugged 1⁄4-28 stud mounting,
and an epoxy seal; and uses the
kind of dependable components
usually found only in higher-priced
accelerometers.
