Click HereThe HK OP-EX20 series LED light source provides higher power, uniform and stable illumination for pressure and temperature sensitive paint measurements. The OP-EX20 series includes three versions: constant light version, pulse version, pulse & constant light version, designed for PSP and TSP measurement system and can operate in continuous mode or pulse mode, using an external toggle switch to set the operating mode. The pulse mode controls operation by applying a TTL voltage through the external BNC of the chassis.
