SP Lite2 Pyranometer for Routine Measurement of Solar Radiation

SP Lite2 has been designed for routine measurement of solar radiation. One can use SP Lite2 in all weather conditions. The solar energy received from the entire hemisphere is determined by the sensor. It is suitable for the measurement of available energy for use in solar energy applications, plant growth, thermal convection and evapotranspiration.

SP Lite2 makes use of a photodiode detector, which creates a voltage output that is proportional to the incoming radiation. Also because of the innovative design of the diffuser, its sensitivity is proportional to the cosine of the angle of incidence of the incoming radiation, enabling precise and consistent measurements.

SP Lite2 can be used easily. It can be connected directly to the data logger or the voltmeter. Direct readout in watts per square meter (W/m²) can be derived from the measured voltage divided by the calibration coefficient. It is fixed with the Kipp and Zonen high quality yellow cable.

SP Lite2 features adjustment screws and a bubble level integrated in the mounting flange for one’s convenience. A threaded hole in the housing body is fitted with the accessory screw-in mounting rod. Two instruments can easily be bolted back-to-back and fitted with a mounting rod to make a simple albedometer.
