About This Product
Students rest the three legs on a curved surface and turn the central screw until it just touches, then repeat on a flat plate; the difference in readings gives the sag, from which the radius of curvature is worked out. The same instrument measures the thickness of a glass slide or thin plate. Enquiries from Niger, Samoa, Montenegro, Zambia and Burkina Faso for the Spherometer receive an export quotation.
