Hydrofarm lg17010 digital light meter. This product is a precision instrument used to measure luminance (footcandles). The meter is fully cosine corrected for the angular incidence of light, meaning that if you are not holding the sensor perfectly perpendicular to the light source, the sensor will still read the light correctly.
The sensor is stable and made of a long-life silicon photo diode. The digital light meter accurately measures to 40,000 FC. 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. The meter’s built-in low battery indicator means you’ll never be caught by surprise by a low-power product.
