CLEAR ANALOG METER NO SCALE DIY

Going Ballistic?

This new take-out analog/ballistic meter, a genuine science device, was intended to measure electrodermal activity in humans, if you're into that kind of thing. (We make no judgments here at the home office, lest we be judged.) Has a clear acrylic elliptical face, 6-1/8" x 4" with a 2-1/4" x 2" x 1-1/4" housing for the mechanism on the rear bottom, along with a pair of screw terminals. No scale, but full deflection is at 125uA.
