SCREENMASTER, HAGNER

The Hagner Screen Master is a small, handy and very easy-to-use instrument for measurement of luminance (measuring angle 36°) and illuminance over a range of 0.1-200,000 cd/m² and lux, respectively. With both automatic zeroing and on/off switch, the only controls needed are a four-position range selection switch, a hold button for retaining the displayed value and a switch for selection between luminance and illuminance. The screen Master is well suited for determination of light quality, e.g. in working areas where image screens are used
