Models 7241C and 7241M
Unidata has a range of radiation sensors which can be directly connected to any IP Datalogger and 7001D Prologger or via a Model 6107B Isolated Input Amplifier Module to a Model 6004D Starlogger. Mostly widely used pyranometer sensor is listed below. Other types of radiation sensors are available on request.
Pyranometer Sensor – Solar Energy Model 7241C
Apogee Instruments pyranometer represent the next generation in pyranometer design maximizing accuracy, reliability and durability.
Featuring a silicon-cell photodiode with excellent cosine response, this pyranometer 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.
SP-212 is a fully potted, domed-shaped head making the sensor fully weatherproof, self-cleaning, and impervious to thermal based accuracy fluctuations.
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.
