Abstract
An environmentally sealed electronic test instrument having a three-part case enclosing an electronic testing circuit of conventional design. The three parts are open-ended top and bottom parts, and an end part covering the open ends of the top and bottom parts. The top and bottom parts have adjoining sidewalls between which is positioned a first resilient seal. Respective inwardly extending flanges are formed at the open ends of the top and bottom parts. The flanges are received by a second, U-shaped seal that is, in turn, received by a U-shaped channel formed along a marginal edge of the end plate. A pair of fingers integrally formed in the second gasket project into the U-shaped channel and are positioned between the first seal and top part of the case. The side marginal edge of the bottom part of the case are recessed within the sidewall of the top part of the case to enclose the first gasket.
