Download of the Instruction Manual
Light Analyzer (LA-105), specially designed for light sources for plants, can easily measure various light sources. Photosynthesis in plant growth highly depends on the quality of light. Various morphogenesis is controlled from seeds to fruition during the plant growth. This hotomorphogenesis is known to require various kinds of light, and thus the light should be precisely measured as photon flux.
Light Analyzer (LA-105) makes it possible to precisely measure photon flux at each wavelength. In monochrome light sources including LED, the best light source and/or photon flux can be selected for plant growth by measuring PPFD.*
Light Analyzer (LA-105) is equipped with a 3.5 inch touch panel and easy-to-use interface. The optical part can be separated from the main body. The data can be stored in a SD card. The obtained data can be easily controlled with dedicated software by connecting LA-105 to a personal computer via USB cable.

The captured data can be saved as an Excel file in a SD card. The following is an example of the Excel data.
