The DLI meter calculates the daily light integral (DLI) and photoperiod. DLI refers to the total number of PAR or ePAR incidents on a plane in a 24-hour period, expressed in units of moles per square meter per day (mol m-2 d-1).
DLI-500 FULL SPECTRUM METER – New for 2022, the DLI-500 from Apogee Instruments is a sleek, easy-to-use device for spot-checking levels of photosynthetically active radiation (PAR; 400-700 nm) and measuring light integral daily (DLI) and photoperiod under all light sources.
DLI-600 ePAR METER the Apogee Instruments' DLI-600 is an elegant, simple-to-use device for spot checking photosynthetically active radiation (PAR) beyond the traditionally 400–700 nm range.
The MP-100 has an integrated sensor on the top of the portable meter that displays and stores measurements in W m-2. Typical applications include shortwave radiation measurement in agricultural, ecological and hydrological meteorological networks and in solar panel arrays.
The MP-200 is a hand-held, cable-connected meter that displays and stores measurements in W m-2. The sensor incorporates a silicon cell photodiode with a rugged, self-cleaning sensor housing design. Typical applications include measurement of shortwave radiation in agricultural meteorological, ecological and hydrological networks and in solar panel arrays.
