Measuring the light necessary for plant growth, photosynthetically active radiation (PAR).
• Portable and easy-to-operate quantum light meter OSK 12TU179 • Measures the light necessary for plant growth, Photosynthetically Active Radiation (PAR) • Measures the wavelength range of PAR from 400 to 700 nm • Measurement unit: Photon flux density (μmol/m²s) • Measurement range: 0 to 1,999 μmol/m²s • Operates on a 9V battery • Low cosine error (70-50% compared to competitors) Overview The wavelengths of light observable by the naked eye have little impact on plant growth. While Lux or candela indicate the light in the Human Eye region shown in the upper left image (approximately 500-600 nm), the wavelength range of 400-700 nm, which is Photosynthetically Active Radiation, includes light quantities in the wavelength band that significantly affect plant growth. By measuring photon flux, it becomes possible to assess and quantify whether plants are receiving sufficient light necessary for their growth. What is light? Wavelength: Light is electromagnetic radiation. Wavelength is expressed in nanometers (nm). Particles: Light consists of photons, which are quanta. Each photon possesses a small amount of energy, and photons are measured in moles (mol), with 1 mol equaling 6.02 x 10²³ photons. μmol is one millionth of a mol.
