Description Measurement and examination of the photosynthetically active radiation, R/FR, DLI, illuminance, luminous color, color rendering index, scotopic to photopic ratio, EVE factor , spectrum of LEDs and other lights The BTS256-PAR 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. Light meter with a precise cosine field of view function BiTec light sensor for precise light measurements One of the outstanding properties...

meets the conditions specified for two of the DIN 5036 quality classes. • In terms of the f2 uncertainty i.e. < 3%, the device corresponds to the quality class B • In applications where limitation of the viewing angle is acceptable, the BTS256-PAR, with its fT, u, f3 and f4 values, corresponds to the quality class A (DIN 5032 section 7). Diverse photometric and colorimetric measurands A much broader diversity of measurands as the one offered by conventional light meters is required for verification and testing of LED lamps. The BTS256-PAR offers fourteen measurands and thereby meets all the requirements...

Protective cap with chain The protective cap for the diffuser window is attached onto the device. Use without PC The BTS256-PAR has all the necessary functions enabling free operation of the device without having to depend on a computer. Furthermore, the rechargeable batteries have a capacity of more than 8 operation hours. The USB power adapter enables recharging of the device without a PC. The measurement parameters protocol is saved together with a measurement data file Use with PC The BTS256-PAR additionally has a USB 2.0 interface for use with a PC. This enables both data exchange and battery...
