The development of the OLAS measuring system, an online measuring system, that determines that solid content of concrete recycling water, was initiated years ago. It has been established into a reliable and economic measuring system reaching product maturity. OLAS, named after its functionality namely: Optical Light Absorption Sensor, makes use of a sophisticated and modernized infrared absorption measuring method, in which the measurement of light is introduced into the medium through optical fibres.
When desired, OLAS can be supplemented by the OLASTPC (OLAS Touch Panel Controller), an optimal evaluation that functions as a display and control unit that forms a complete measurement system.
