Hortivision Par Meter + Extendable Measurement Stick thermometers-hygrometers Includes calibration-free Conductivity ProbeThe HORTI VISION PRO SERIES 2 QUANTUM PAR METER is crafted to measure PAR (Photosynthetically Active Radiation) flux across wavelengths spanning from 400 to 700nm. This meter relies on the correlation between photon absorption within this spectrum and the photosynthesis rate in plants. Such measurements are crucial for horticultural research and tracking plant physiology. BOX CONTENTS: OPERATING INSTRUCTIONS: LIGHT INTENSITY GUIDE FOR PLANTS: * Please
