A well-balanced vane rotates in response to an electrical charge. The angle measurements printed on the back show different positions in increments of 10 degrees up to 90°. The stronger the charge the greater the deflection.\n\nThe metal case has a diameter of 5” and is 3” deep to help reduce the influence of air currents. The top plate is 3” in diameter.
