Important features : ISO 9060:2018 - fast response, class C Low-cost instrument for routine measurement of solar radiation Reliable all weather performance Easy to use

The SP Lite 2 Pyranometer (ISO 9060:2018 - fast response, class C / formerly ISO 9060:1990 second class) is designed for routine measurement of solar radiation.

It is especially designed for:

• Photovoltaic / solar energy module monitoring
• Agricultural evapotranspiration estimation
• Air pollution dispersion calculations using the Delta-T method
• Educational purposes

The SP Lite 2 can be used under all weather conditions. The sensor measures the solar energy received from the entire hemisphere. It is ideal for measuring available energy for use in solar energy applications, plant growth, thermal convection and evapotranspiration.

The SP Lite 2 uses a photodiode detector which creates a voltage output that is proportional to the incoming radiation. Also due to the unique design of the diffuser, its sensitivity is proportional to the cosine of the angle of incidence of the incoming radiation, allowing accurate and consistent measurements.
The instrument is easy to use. It can be directly connected to a voltmeter or a data logger. Direct readout in Watts per square meter (W/m²) can be derived from the measured voltage divided by the calibration coefficient. It is supplied with a captive cable of 5 or 15 m.

The SP Lite 2 features adjustment screws and a bubble level integrated in the mounting flange for your convenience. A side threaded hole in the housing body accommodates the screw-in mounting rod # 0338720, available as an accessory. Two instruments can easily be bolted back-to-back and fitted with the mounting rod to obtain a simple albedometer.

The pyranometer does not require any power. His output signal is a low voltage around 0 - 100 mV in relation to the amount of incoming radiation. When a higher signal level (0,2 - 1 V or 4 - 20 mA) is required, the choice of an AMPBOX has to be considered.
