These rugged handheld solar irradiance meters not only measure irradiance, but also have a built-in inclinometer to measure roof pitch, compass to measure roof orientation and thermometer to measure ambient air and module temperature. These unique additional features makes the Solar Survey 100 and 200R truly versatile and indispensable instruments, ensuring optimum conditions for every system you install.
These high specification irradiance meters simply and quickly measure irradiance, displaying the information in either W/m2 or BTU/hr-ft2, making them ideal for both solar photovoltaic (Solar PV) and solar thermal applications.
The use of a photovoltaic reference cell, provides a more representative measurement of solar energy and greater accuracy and repeatability compared to irradiance meters which use simple photo diode detectors.
The Solar Survey 100 incorporates a display hold feature, which enables the user to easily capture readings in difficult locations.
