The LPS06 Albedometer is a robust, cost-effective solution for measuring solar radiation and surface albedo. It integrates two ISO 9060:2018 Class C thermopile pyranometers (upward and downward facing) to simultaneously capture incident and reflected solar energy. This passive instrument requires no power supply, features an integrated bubble level for easy installation, and is ideal for climatology, agriculture, and environmental monitoring. Delivering reliable data for calculating albedo and net radiation, it's a practical choice for continuous field deployment in various weather conditions.
Essential Environmental Data with Cost-Effective Precision
The LPS06 Albedometer provides critical insights into the earth's energy balance by measuring both incoming and reflected solar radiation. This dual-sensor design is fundamental for calculating albedo—the reflectivity of a surface—which is a key parameter in understanding climate patterns, agricultural water use (evapotranspiration), and snow/ice melt processes. Designed for integration into Automatic Weather Stations (AWS) and environmental research networks, it offers a perfect balance of performance and value for long-term monitoring projects.
Built for Simplicity and Reliability in the Field
Engineered for hassle-free operation, the LPS06 eliminates the complexity of power supplies and active electronics. Its completely passive design ensures maximum uptime and minimizes maintenance. The sturdy construction, featuring an anodized aluminum housing and optical glass domes, provides excellent durability against harsh environmental conditions, from extreme heat to freezing temperatures. The integrated bubble level guarantees a quick and accurate horizontal setup, which is crucial for obtaining valid and comparable scientific data.
Key Advantages & Features
- Dual Class C Accuracy: Equipped with two Spectrally Flat Class C pyranometers (ISO 9060:2018) for reliable measurement of global and reflected solar irradiance.
- Passive & Zero-Power Operation: Requires no external power, simplifying installation in remote locations and ensuring continuous data collection without energy needs.
- Integrated Leveling Tool: A built-in bubble level (<0.2° accuracy) facilitates a correct and swift installation, ensuring measurement accuracy from the start.
- Factory Calibrated: Each unit is supplied with an individual calibration report, providing traceability and confidence in the measurement data right out of the box.
- Durable IP67 Design: Built to withstand harsh environments with an operating range of -40°C to +80°C and 100% RH, protected by an IP67 rating.
Measures & How to Use
- Primary Application: Perfect for agricultural meteorology, climatological studies, hydrology, and educational environmental monitoring projects.
- Mount the unit on a mast in an open area using the provided fixing support. Use the integrated bubble level to achieve a perfectly horizontal orientation.
- Connect the two separate sensors to a data logger using the 2.5-pole M12 connectors and appropriate cables (ordered separately).
- The instrument outputs a analog millivolt (mV) signal. Apply the unique calibration factors from the provided report to convert these signals to W/m².
- Calculate Albedo = (Reflected Radiation / Incident Radiation). Derive Net Radiation = Incident - Reflected.
