Light Meter with Wi-Fi

NEWBURYPORT, Mass., June 27, 2014 — A WiFi interface has been added to the BTS256-E light meter from Gigahertz-Optik, allowing wireless control of all meter functions to characterize long-distance light sources from a central location.

The BTS256-E WiFi measures fifteen different quantities, including photopic and scotopic illuminance, S/P ratio, Equivalent Visual Efficiency factor, color coordinates, CT, CRI, color purity, deltaUV and spectral irradiance. A Bi-Technology sensor includes a precision photometric photodiode and diode array spectrometer.

Any spectral mismatch error of the photopic sensor is compensated on-line using the diode array’s measured spectral data. This reduces measurement uncertainty when evaluating light sources. A built-in electro-optical shutter for dark-signal pixel offset compensation optimizes signal-to-noise ratio to increase the linear dynamic range of the C-MOS diode array detector.

Applications include lighting design, engineering, manufacturing and maintenance.
