The TBB Net Radiometer is a high-precision research-grade instrument designed for meteorological and environmental monitoring. It measures the net difference between downward sky radiation and upward terrestrial radiation, covering shortwave radiation (0.3–3 μm), longwave radiation (3.5–50 μm), and their reflectivity. Integrated with algorithmic temperature compensation and robust stability, it ensures accurate and reliable data for scientific and industrial applications requiring detailed radiation energy exchange analysis.
High Accuracy & Fast Response: Sensitivity of 7–14 μV/W·m² (shortwave) and 2–10 μV/W·m² (longwave), with response time ≤12 seconds and non-linearity ≤±5%.
Smart Temperature Compensation: Utilizes a PT100A-grade platinum resistor combined with algorithmic compensation, surpassing traditional single-resistor methods to mitigate environmental fluctuations.
All-Weather Reliability: Operates in temperatures from -40°C to +80°C and 0–100% RH, with annual stability ≤±2%, ensuring performance in extreme outdoor conditions.
Multi-System Compatibility: Supports 0–20 mV analog output and RS485 MODBUS digital communication for seamless integration into data acquisition systems.
