Description:
  • Made by the company Mechanism Ltd in 1963. An aneroid barometer in which the movement of the face of the evacuated capsule is shown, not by means of a train of pivoted levers attached to a pointer, but by the deflection of one light, pivoted, counter-balanced electrical contact arm mounted in jewelled bearings. Electrical contact is established by manually rotating a micrometer screw. The reduction in backlash and friction greatly increases the accuracy of this instrument. This instrument is fixed into a wooden box with metal hinges and leather strap handle. Operating instructions are attached to the box and visible when the box is opened. Both the box and the instrument have the reference and serial numbers attached. Ref No. MET. 20.000, Serial No. 380/63
