【Quantum Par Meter】This fully portable handheld PAR meter features our highly accurate, integrated Quantum Sensor that measures PAR (Photosynthetically Active Radiation) flux in wavelengths ranging from 400 to 700 nm. It measures up to 10,000 μmol/s compared with 2,000 μmol/s for other meters on the market.
【Save Money:】 Best selling AND useful for your indoor growing plants and 3.get you in the ball park of light requirements and testing for half the cost.
【All Indoor plants】 Data logging capability, 2xAAA batteries.
【High Precision】 Constant linear response curve (as opposed to other meters' Gaussian response) yields higher accuracy independent of wavelength—perfect for measuring LED light output.
【Free return/exchange/refund if any concern】upraged to 2 years warranty.
