Overview

The Senseca LPS110P0 is a Spectrally Flat Class A albedometer designed for high-accuracy solar reflectance and net solar radiation measurement. It consists of two independent LPS100P0 thermopile pyranometers, one facing upward to measure global solar radiation and the other facing downward to measure reflected solar radiation. The sensors comply with ISO 9060:2018 and meet WMO recommendations.

The albedometer provides a measuring range of −200…4000 W/m² and a spectral range of 283…2800 nm. Each pyranometer delivers a passive mV output through a separate 5-pole M12 connector without requiring an external power supply. Designed for outdoor monitoring, it features IP67 protection, an anodized aluminium housing, optical glass domes and an integrated bubble level for accurate horizontal positioning. Both sensors are factory calibrated according to ISO 9847:2023 and supplied with a calibration report including temperature and directional response measurements.

Solar reflectance and albedo measurement
Net solar radiation monitoring
Climatological research
Automatic weather stations (AWS)
