The TBQ-2H Total Solar Radiation Sensor (Class A), also known as a pyranometer, specializes in measuring the total radiation (shortwave) received on a horizontal plane, which includes direct solar radiation and scattered radiation. This device is specifically designed for solar resource assessment, environmental monitoring, and climate research, offering comprehensive and accurate measurement capabilities to provide users with detailed solar resource data. Its high-precision and high-stability measurement performance, coupled with its simplicity and ease of use, as well as convenient maintenance, make it an ideal choice for outdoor environments such as meteorological stations, agricultural test fields, and solar power stations.

PRODUCT FEATURES
1. According to ISO9060 and WMO technical indicators, it meets the Class A standard.
2. The adoption of high-precision thermopile semiconductor processing technology ensures higher, more stable, and more accurate overall batch performance and measurement precision.
3. The high-quality 1mm protective cover and fully enclosed design can prevent the impact of external environment.
4. Fast response speed, low internal resistance, and rapid reaction speed ensure accurate data.
5. Data calibration can be performed around the clock, even in various weather conditions such as sunny, cloudy, and overcast, ensuring more accurate data.
6. High-precision horizontal bubble processing for fine anchor screws, with point-like grounding for more precise horizontal adjustment.
