Our Class A/B Pyranometers deliver laboratory-grade accuracy for solar radiation measurement, engineered to match stringent ISO 9060:2018 standards. The Class A sensor (≤2% uncertainty) meets research-level demands, while Class B offers industrial reliability at competitive pricing. Designed as a high-performance alternative to OTT pyrnometers, they combine low thermal drift, broadband spectral response (280-3000nm), and ruggedized construction for permanent outdoor deployment.

◀◀ Key Selling Points ▶▶

· Class B is the classification of the sensor according to the standards set by the International Organization for Standardization (ISO).

· Class B sensors are suitable for general solar radiation measurements but offer lower precision compared to Class A sensors.

· Class A sensors are typically used for highly accurate, reference-grade measurements in research and calibration, while Class B sensors are more cost-effective and still provide good accuracy for many applications, including solar energy monitoring.

Why Class B?

· Cost-Effective Precision: Offers sufficient accuracy for non-critical applications, avoiding the higher cost of Class A.

· Real-Time Capability: Enables immediate decision-making in dynamic systems like smart grids or automated buildings.

· Versatility: Suitable for diverse sectors needing reliable solar data without ultra-high precision, from agriculture to urban planning.

How It Works

Thermopile Sensing Core:

Converts absorbed solar energy (W/m²) into a millivolt signal via a black-coated thermopile, ensuring uniform spectral absorption.
Dome-shielded design minimizes cosine error for accurate diffuse/direct radiation measurement.

Smart Output & Compensation:

Active temperature compensation maintains ±1% stability across -40°C to +80°C.
Configurable outputs: 4-20mA, 0-5V, or RS485 (Modbus RTU) for seamless integration with SCADA/IoT gateways.
