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 sensor to 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 data logger.
Two LP02 pyranometers can be mounted back-to-back to make a low-cost albedometer. Contact Campbell Scientific for more information.
Because the LP02 is a second-class pyranometer, it is acceptable for providing the solar radiation data used in stability estimations
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 levelling screws, eliminating the need for a separate levelling base and simplifying installation
- Acceptable for providing the solar radiation data used in stability estimations
- Dome protects thermopile and allows water to roll off of it
- Designed for continuous indoor and outdoor use
The LP02, manufactured by Hukseflux, is an ISO 9060:2018 spectrally flat Class C (second class) pyranometer that monitors solar radiation for the full solar spectrum range. It produces a millivolt signal that is measured directly by a Campbell Scientific data logger. The LP02 can provide solar radiation measurements for a variety of meteorological applications.
