Abstract: A clamshell housing is used in a stand-alone configuration of “DualPlay” instrument modules. The housing comprises first and second sections pivotally connected by a hinge mechanism at a hinge end of the clamshell housing that allows rotation of the first and second sections relative to one other between an open and closed position. An open end of the clamshell housing is opposite to the hinge end. A sliding-fastener bumper section slides over the open end and secures the sections in the closed position. A main storage compartment is formed by the first and second sections when in the closed position and serves to hold the instrument module.

Abstract: An instrument module “DualPlay” housing system includes a first instrument module which is constructed from a measurement board enclosed by a first protective instrument module casing. The first instrument module is additionally enclosed in a main storage compartment of a housing. Additional instrument modules are enclosed in additional housings. Securing sections at the tops and bottoms of the housings secure the housings in a vertical stacked configuration.
