ISO 9060:2018 Class B pyranometers for reliable solar radiation measurement in commercial solar farms, weather networks, and environmental monitoring. Features thermopile technology with ±2% uncertainty and 7-15 µV/W/m² sensitivity. Ideal for PV performance assessment, agricultural meteorology, and educational research. Weather-resistant design with IP67 protection and optional heating.
Commercial-Grade Solar Monitoring Solutions
LSI Lastem Class B pyranometers deliver cost-effective precision for solar energy applications. Engineered to ISO 9060:2018 standards, these instruments measure global horizontal irradiance (GHI) from 300 to 2800 nm using black thermopile detectors. The single glass dome design with temperature compensation ensures stable performance in outdoor environments from -40°C to +80°C. Perfect for solar plant operators needing bankable data for performance guarantees.
Practical Application Scenarios
Solar energy: Monitor PV system yield and detect underperforming modules. Weather stations: Integrate into automated networks for regional solar mapping. Agriculture: Calculate evapotranspiration rates for irrigation planning. Education: Teach renewable energy concepts in university labs. Building management: Validate daylight-responsive lighting controls in commercial structures.
Key Operational Advantages
- Low thermal offset (＜±5 W/m²) with passive temperature compensation
- Anodized aluminum body with corrosion-resistant mounting hardware
- Integrated bubble level for fast field installation
- Optional heating system for snow-prone regions
Installation & Maintenance Protocol
Mount horizontally with unobstructed 180° view of the sky. Clean dome monthly using distilled water and soft cloth. Verify leveling quarterly and recalibrate every 24 months. For winter operation, enable heater when temperatures drop below 3°C. Avoid shading from nearby structures or vegetation. Store calibration certificates with serialized unit history.
