Gossen, inventor of the photo-electric light meter and renowned German manufacturer of advanced measurement equipment, settles on Hensel technology to check and calibrate their professional flash meters.
After testing many different products, Gossen decided on a Hensel Tria generator: Power and color stability of these units are exemplary constant. Hensel did modify the Tria to make it compatible with Gossen’s calibration device. On top a special flash head was constructed – based on the standard LightStick – to gain a point light source optimized for the control installation at Gossen’s production plant.
We are proud to manufacture the reference flash for such a demanding application and sophisticated customer.
