Quantity

Overview

The Senseca LPS060P0 is a Spectrally Flat Class C albedometer designed to measure incoming and reflected solar radiation for determining surface albedo and net solar radiation. It combines two independent LPS030P0 thermopile pyranometers, one facing upward and the other downward, with a measuring range of −200…4000 W/m² and a spectral range (50%) of 300…2800 nm. The pyranometers are classified according to ISO 9060:2018 and meet WMO recommendations.

The albedometer operates without an external power supply, providing separate passive mV outputs through two 5-pole M12 connectors for connection to a suitable data logger or reading instrument. It features IP67 protection, an anodized aluminium housing, an ASA solar radiation protection screen, optical glass domes and an integrated bubble level for accurate horizontal positioning. Each pyranometer is factory calibrated according to ISO 9847:2023 (Type A1) and supplied with a calibration report.

Typical Applications
