Apogee Instruments pyranometers represent the next generation in pyranometer design maximizing accuracy, reliability and durability. Featuring a silicon-cell photodiode with excellent cosine response, our pyranometers measure total solar radiation to within ±5% at a fraction of the price of black-body pyranometers, and at a far lower price-point than most other photodiode pyranometers on the market due to advancements in manufacturing.
Our pyranometers feature a fully potted, domed-shaped head making the sensor fully weatherproof, self-cleaning, and impervious to thermal based accuracy fluctuations. Apogee’s latest pyranometer design is the culmination of over 16 years of field-testing and feedback from scientists all over the world. Apogee also subjects all sensor designs to unprecedented extreme accelerated aging tests to eliminate any weaknesses or design flaws. Read about our accelerated aging tests in detail here.
To ensure accuracy, each Apogee pyranometer is carefully pre-calibrated in controlled conditions and traceable to ISO class reference standards so your sensor is ready to go right out of the box. Our stock sensors come in several configurations and are readily compatible with most data-loggers. Our custom options can provide maximum flexibility by offering different multipliers, outputs, and cable lengths. With Apogee, you are dealing directly with the manufacturer and we can work with you to ensure a pyranometer that fits your specific need, no matter how large or small.
