The SPF series SPECTRAL FLICKERING IRRADIANCE METER is a portable and rapid test device developed for the on-site health lighting inspection, which is composed of spectral, flicker, Lx, plant growth lights and chromaticity inspection. It improves the spectral mismatch of traditional lux meter and colorimeter, and has good measurement linearity and accuracy.

SPF series SPECTRAL FLICKERING IRRADIANCE METER is small and easy to carry, with WIFI function, which can realize the separation of host and sensor for long-distance flexible measurement; Built in battery and memory card, which can be measured and saved at any time; Large touch screen can realize human-computer interaction. It is applicable to the working environment of outdoor and indoor scenes to achieve the purpose of rapid measurement.

lumeter measurement

Lux, average lux.

Spectrometer measurement 

Color Coordinate（x，y 、u',v '),Relevant Color Temperature (CCT), ColorRendering ,Index(Ra), Color Tolerance (SDCM), Wavelength, Color purity, Color saturation (Rg),

Color fidelity (Rf), Color ratio (RGB), Light dark visual ratio (S/ P).  

Stroboscopic measurement

Flick, Flick Index, Flick percentage,Modulation Depth, CIE SVM , ASSIST MP, IEC-Pst, CA CEC, IEEE Std1789.   

Plant growing lamp measurement 

Photosynthetic effective radiation (PAR), Photosynthetic photon flux density (PPFD), red blue ratio and Chlorophyll A / B.

○ Millisecond precision measurement including spectral radiance, irradiance and chromaticity, Lx, average Lx, multiple standards of light source flicker and plant growth lamp parameters. 

○ The sampling frequency of light source flicker test can reach 20kHz at most. With high FFT resolution, it can accurately complete the measurement of multiple parameters such as Flicker index and Flicker percentage.

○ Sensor can be connected flexibly, which can be integrated with the host, or separated from the host and connected wirelessly to realize remote measurement. In the case of radiation exposure hazards, it can avoid direct radiation exposure, making the measurement more flexible and safe.
