At Apogee Instruments, our mission is to help you make better measurements. This means more than just creating and selling research-grade sensors at an excellent price. It involves understanding your needs, supplying solutions, and providing the world-class support you need to succeed no matter the size of your project.
Our job isn’t done when your product ships. As you can see, we invest significant resources in developing support materials to clearly explain how to use our products optimally for years to come. If you can’t find an answer to your question on our site or in a manual, our highly trained technical-support specialists are standing-by to answer your questions by phone or email. We value interaction with our great customers and view you as a critical partner on the front-lines of your field.
Apogee offers two types of pyranometers; our original silicon-cell models and our new line of thermopile pyranometers, both of which are now ISO 9060:2018 Class C rated (previously known as second class). Silicon-cell solar radiation sensor models are excellent for applications that do not require the higher accuracy and cost of a thermopile pyranometer. They are less expensive and have a faster response time, but have higher errors under cloudy conditions. Our new cost-effective thermopile pyranometers features a blackbody thermopile detector that provides a much broader and more uniform spectral response for better performance in all atmospheric conditions that compares favorably to other thermopile pyranometers at a fraction of the cost. Applications include shortwave radiation measurement in agricultural, ecological, and hydrological weather networks, measurement of global solar radiation, and optimizing photovoltaic systems.
