Spectrally flat Class A pyranometer with sapphire outer dome
SR25 takes solar radiation measurement to the next level. Using a sapphire outer dome, it has negligible zero offsets. SR25 is heated in order to suppress dew and frost deposition, maintaining its high measurement accuracy. When heating SR25, the data availability and accuracy are higher than when ventilating traditional pyranometers. In addition, SR25 needs very low power; it only consumes 1.5 W compared to the usual 10 W for ventilation. The low thermal offsets make SR25 very suitable for measuring diffuse radiation.

Best data availability
By keeping the outer dome of the SR25 free from dew and frost with the help of the internal heater, data availability is greatly increased compared to traditional pyranometers, whether ventilated or not. The application photo shows the clear difference between the SR25 and an unheated pyranometer without a sapphire dome.
Best measurement accuracy
The SR25 measures solar radiation received by a flat surface, in W/m², from a field of view angle of 180°. The SR25 offers the best measurement accuracy: the specification limits of two main sources of measurement uncertainty have been greatly improved compared to competing pyranometers: “zero offset to” and temperature response.
SR25 design
The SR25 has a sapphire outer dome, a glass inner dome and an internal heater. It employs a state-of-the-art thermopile sensor with a black-coated surface and an anodized aluminum body. The connector, desiccant holder and sun shield attachment are very robust and designed for long-term use.
