This fully portable handheld PAR meter uses a high-precision integrated quantum sensor to measure PAR(photosynthetic active radiation) flux in the wavelength range of 400 to 700 nanometers. 

Best-selling and suitable for indoor growing plants. Light requirements to allow you to enter the stadium, and tested at half the cost.

Data recording function, using standard mini USB data cable and proprietary data recording software and low power consumption, built-in low power indicator.

Constant linear response curve (as opposed to the Gaussian response of other meters) results in higher accuracy and no wavelength, which is ideal for measuring LED lamp output.
