Working very closely with Cirrus design engineers we have produced a range of keypad
For Sound Level Meters. The Optimus hand held device is a Keyflex design with laser etched
legends back-lit via SM / LED’s on an integral FPC. The very large Invictus keypad (230 x 300 mm) is fitted to the top of an outdoor heavy duty instrument case. A water proof integral hinge section is included to give access to connectors.
