The Concept OPL 100 unit is designed to measure the density of smoke, dust, mist or fog between a given area. The system is low maintenance, double pass, dual beam transmissometer that consists of a transceiver (transmitter / receiver), and a passive retroreflector module. These components are stack mounted which are then interfaced with the control unit. The transceiver produces an electronically modulated and collimated light beam which is projected across the given area to a retroreflector that returns the beam back to the transceiver where the light beam intensity is measured by a measurement detector (MD). This detector will only measure the modulated light and is not affected by the presence of stray or artificial light.

The only two options available from current technologies for density measurement are Opacity and Optical Density - the Concept OPL 100 offers both.

The resulting report noted:
"With the visual aid of white smoke emitting from leakage areas, this was a quick and easy task to accomplish (< 10 minutes)."
It went onto conclude:
"Use of smoke as a means by which to detect cabin pressurization leaks has been shown to be extremely effective and is unquestionably superior to any alternative detection method used to date."
