PRODUCT DESCRIPTION
The TBS-3 Fully Automatic Sun-Tracking Direct Solar Radiation Pyrheliometer is a domestically developed unattended instrument for measuring direct solar radiation. Its user-friendly design makes solar radiation measurement simple and efficient. With no need for daily adjustments or continuous maintenance, you only need to install it at the measurement site to accurately obtain direct solar radiation data at different times throughout the day.
1 Measures direct solar radiation within a spectral range of 0.28 μm to 3 μm.
When the direct solar radiation exceeds 120 W/m², it can be connected to a data logger to directly measure sunshine duration.
2 Equipped with angle sensors and a quadrant photodetector balance system, enabling automatic tracking of the sun’s movement.
The solar azimuth and elevation angles are continuously adjusted, allowing 全天候 (all-day) automatic sun tracking.
3 The optical tube consists of a light baffle, inner tube, and desiccant.
The sensing element uses a multi-junction electroplated thermopile, with triple protective surface treatment, ensuring reliable long-term outdoor operation.
4.Compared to semi-automatic models, no adjustment or maintenance required; delivers accurate measurements at any location.
5.Dual-axis tracking design with certified patents; reliable and accurate even in harsh outdoor environments.
6.Aviation-grade connectors for high durability, excellent insulation, and safe operation.

Unattended, fully automatic sun tracking
Maintenance-free, all-weather operation
Weather-resistant with high-precision measurement
No calibration required, efficient data monitoring
