Open the catalog to page 1Description BTS256-E - mobile light meter for photopic and scotopic illuminance, EVE factor, luminous color, color rendering index and luminous spectrum The BTS256-E is a high-quality light meter that is well suited for illuminance and luminous color measurements in all application areas thanks to its compact design, high-quality light sensor and precise cosine field of view function. BiTec light sensor for precise light measurements One of the outstanding properties of this mobile light meter is its BiTec light sensor. This combines the characteristic properties of a silicon photodiode...

Vision scientists have demonstrated unequivocally that melanopic light reception affects brightness perception and that the conventional photopic measurements require a correction to maintain a proper correlation...
Open the catalog to page 3measurement points can be progressively processed and saved. • Fast data logger measurement mode where time-clocked readings of the photodiode can be recorded at a maximum measurement rate of up to 100ms. • A second data logger measurement mode that enables time-clocked recording of all measurands including the spectral measurement data. • Date and time in real-time can also be set. Tripod mount The measurement device has a tripod stand socket on the bottom side. Protective cap with chain The protective cap for the diffuser window is attached onto the device. Option WiFi With this option...
