This digital light meter measures ambient illuminance across three selectable ranges: 2,000 lux, 20,000 lux, and 50,000 lux. The silicon photodiode sensor includes two filters and meets C.I.E. photopic spectral response standards for accurate visible-light measurement. The meter reader measures 4.25 x 2.75 x 1 inches, and the remote sensor measures 4 x 2.25 x 1 inches with a cord that extends to approximately 35 inches. The remote sensor design allows measurements in tight spaces or at angles without repositioning the display. Includes a 9V battery, black snap carrying case, and instruction manual.
