Dustproof and drip-proof spectrometer / Model number M51SP-926M
This is a visible light spectrometer that integrates functions such as a quantum light meter, spectrometer, and color illuminance meter, making it ideal for evaluating plant growth environments.
● Spectrum display mode: Comparison display up to 4 measured wavelengths is possible. ● Color rendering evaluation mode: CIE 1931 chromaticity coordinates, black body trajectory, color temperature, color rendering index. ● Energy measurement mode: Illuminance in Lux, PPFD photosynthetic photon flux density in μmol/m²/s, color temperature in K. ● Calibration via numerical input is possible.
basic information
By installing dedicated software on a WinPC, you can easily measure various data on your PC just by connecting to a USB port. The measurement results can be saved as CSV data or PNG image data. With a waterproof structure and a cable length of about 1.5m, you can measure the PPFD inside an artificial weather device from the outside. When connected to a Win10 tablet PC, it becomes a portable measuring device. Using a super compact CMOS sensor with a diffraction grating manufactured by Hamamatsu Photonics, it measures wavelengths from 340 to 780nm, and the PPFD and illuminance in Lux are calibrated against the latest model from Li-Cor, which is well-regarded in plant research. It traces the action curve of photosynthetically active radiation, allowing for high-precision measurements. Additionally, you can easily calibrate it by simply entering the values from your existing illuminance meter.
