basic information
By installing dedicated software on a WinPC, you can easily measure various data on your PC just by connecting to the USB port. The measurement results can be saved as CSV data or PNG image data. With a drip-proof 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 made by Hamamatsu Photonics, it measures wavelengths from 340 to 780nm, and the PPFD and illuminance Lux are calibrated against the latest model from Li-Cor, which is well-regarded in plant research. Since it traces the action curve of photosynthetically active radiation, it can measure with high precision. Additionally, you can easily calibrate it by simply entering the values from your existing illuminance meter.
