The new Apogee ePAR (extended photosynthetically active radiation) sensor was created to measure the wider 400-750 nm radiation range that cutting-edge research is showing to be photosynthetically active, beyond the traditional 400-700 nm range defined by McCree. Most of this transformative work to refine and define the ePAR range is being conducted by Dr. Shuyang Zhen and Dr. Bruce Bugbee at ...

Apogee SQ-500 sensors are calibrated through side-by-side comparison to the mean of four transfer standard sensors under T5 cool white fluorescent lamps. The transfer standard sensors are calibrated through side-by-side comparison to the mean of at least four quantum sensors under T5 cool white fluorescent lamps traceable to the National Institute of Standards and Technology ...

Apogee Instruments PAR meters are the tool of choice for cost-effective, scientific-grade measurement of underwater PARlevels. Accurate tank PAR mapping, daily light integral measurements, and the adjusting of photosynthetic radiation levels tomimic nature are all critical to specimen health. Apogee offers three different underwater calibrated meters at three differentprice points. The basic ...

Apogee’s NDVI sensors are designed to measure reflectance in red and near infrared wavebands to calculate the normalized difference vegetation index (NDVI). NDVI is a measurement of plant greenness correlated with canopy chlorophyll content and leaf area that is used to monitor green-up in the spring and senescence in the ...

The new Apogee PAR-FAR sensor is a research-grade tool for measuring both the traditional PPFD photosynthetic photon flux and separately quantifying the photon flux of far-red photons (700-760 nm). The outputs include the traditional quantum flux, the far-red photon flux, and the far-red fraction (far-red photon flux density / sum of PPFD and far-red photon flux density). This sensor quantifies ...

Apogee Red - Far-Red sensors combine two photodetectors designed to measure wavelength ranges and peaks that approximate phytochrome absorption. The red / far-red ratio can be calculated from these measurements. Red and far-red wavelengths are of particular interest because they influence photosynthetic and morphogenic activity. Phytochrome pigments sensitive to varying ratios of red and far-red ...

Apogee line quantum sensors measure a spatial average of photosynthetically active radiation. The MQ-301X has a separate sensor bar with 10 sensors, while the handheld meter displays and stores measurements. The sensor housing design features an integrated bubble level and is fully potted, making the sensor water- and ...
