Benefits and Features

Compatible with most Campbell Scientific data loggers

Measures reflected solar radiation when inverted

Provides measurements in direct sunlight, under plant canopies, when the sky is cloudy, and in artificial light

Includes bubble level and leveling screws, eliminating the need for a separate leveling base and simplifying installation

Acceptable for providing the solar radiation data used in stability estimations

Dome protects thermopile and allows waterto roll off of it

Designed for continuous indoor and outdoor use

Technical Description

The LP02 measures solar radiation with a high-quality blackened thermopile protected by a dome. The blackened thermopile provides a flat spectral response for the full solar spectrum range, which enables the LP02 to be used under plant canopies or lamps, when the sky is cloudy, and for reflected radiation measurements.

The LP02 includes a bubble level, three adjusting screws, and a cable gland. The bubble level and adjusting screws allow the sensorto be levelled without using a levelling base. The gland facilitates cable replacement. The LP02 produces a millivolt signal that is measured directly by a Campbell Scientific datalogger.

Two LP02 pyranometers can be mounted back-to-back to make a low-cost albedometer; contact Campbell Scientific for more information.
