Technical Description

SP LITE2 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 for accurate and consistent measurements.

SP LITE2 is easy to use. It can be directly connected to voltmeter or 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 fitted with the Kipp & Zonen high quality yellow cable.

SP LITE2 features adjustment screws and a bubble level integrated in the mounting flange for your convenience. A threaded hole in the body of the housing takes our accessory screw-in mounting rod. Two instruments can easily be bolted back-to-back amd fitted with a mounting rod to make a simple albedometer.

The SPLITE2 includes a bubble level and adjusting leveling screws, which allow the sensor to be leveled without using a leveling base. The 015 Mounting Arm can be used to mount the sensor to a mast or the CM225 Solar Sensor Mounting Stand can be used to attach the sensor to a mast, crossarm, or pole (1.0-in. to 2.1-in. outer diameter). The CM225 consists of rectangular plate, mounting bracket, U-bolts, lock washers, and nuts.

Alternatively, the CM245 Adjustable Angle Mounting Stand may be used. It includes slots that can be adjusted to any angle from horizontal to vertical.
