The new meters however, will work even better when their measurements are multiplied by the new immersion correction factor that is spelled out in the owner’s manuals.  Apogee Instruments designed the MQ-210 and MQ-510 just to make PAR calculations a little easier on the aquarist.  Apogee Instruments tells
