![]() ![]() Up to five user experimental spectral weighting functions can be self-programmed into the PAR meter using the supplied S-BTS256 software and are saved in the PAR meter memory for continued use. User Specific Weigthing Functions for individualized PAR Measurements The end result is much more complete, accurate absolute PAR, light, color and spectral measurement of LED based and other grow lights to investigate the effect of spectral tuning in the horticultural world. The silicon photodiode is equipped with a photopic filter with further improvement of its spectral match to the photometric V(λ) response by the diode array’s spectral measurement data in real time. Silicon Photodiode Detector, Fast and Linear Please see also our technical article about PAR measurements and the PAR implementation in PAR Meters. The BiTec sensor guarantees accurate PAR, photometric and spectroradiometric measurement values over a large dynamic range through mutual correction of the measurement signals of both sensors. ![]() Gigahertz-Optik’s BiTec Sensor technology combines the wide dynamic range, unsurpassed linearity and fast response times of a silicon photodiode with those of a low-noise CMOS diode array. One unique feature of the BTS256-PAR meter is its BiTec Sensor for increased accuracy when measuring LED based or any other artificial or natural light source. A full listing of its light and LED measurement quantities is shown below. The BTS256-PAR meter also serves as a high quality light, color and spectral meter. Advanced features and functions along with hand-held portability enable on site or lab level measurement and datalogging of PAR, PPFD, R/FR, DLI in plant growth, soil science, horticulture and aquiculture applications.
