PPFD Meter Plant Grow Par Light Meter

PPFD Meter stands for photosynthetic photon flux density and it does more than just measure the PPF,  it’s important to make sure that the PPFD data you get from your grow light manufacturer is accurate and covers the entire area of the light. It’s relatively easy to massage this information, so consider factors such as distance from the light source

Resolution: 1umol/m2.s

Unit：umol/m2.s  is photosynthesis rate, 1mW/cm2=46umol/m2.s 

Error range：±(10%R+2dgt)  R: reading (detecting a composite light source that approximates the sunlight spectrum)

The reading error will increase under incandescent lamp or monochromatic yellow light.
