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.
