A quantum refers to the amount of energy

carried by a photon.

Quantum meters approximate the quantity

of photons between 400 and 700 nanometers.   

 

Photosynthesis is largelydriven by the number of

photons between  these wavelengths,

so this radiation  is called

Photosynthetic Photon Flux (PPF)

and is measured in μmol m^-2 s^-1.

  

 

 

As shown in the graph above,

quantum response by definition

is from 400 to 700 nm and

gives equal emphasis to all

photons in that range.

The spectral response of the Apogee sensor,

as well as a typical response, are also shown.

 

 ◆Features

 

MQ Quantum light meters include

data recording capability and

sun and electric calibration

with each meter can store

up to 99 manually recorded

measurements.

In automatic mode,

measurements are made

every 30 seconds and

averages are stored

every 30 minutes.

Daily totals are also calculated and

the past 99 days are recorded.

These meters still feature blue lens for

improved spectral response along with

cosine-corrected head, self-cleaning

characteristics, and long-term stability.
