General Tools DBTU1300 Digital Solar BTU Power Meter

The General Tools DBTU1300 provides accurate solar power measurements for professional and scientific use. This handheld digital meter measures solar power intensity in both watts per square meter (W/M2) and BTU/(ft2 x h), making it a versatile tool for various industries. Whether you are working in meteorology, agriculture, or solar power research, this device delivers reliable data via a clear 4-digit LCD display. Designed for precision, the meter features a silicon photodiode with cosine angular correction. This ensures accurate readings of solar power radiated from any direction, angle, or position, with less than 5% error for angles under 60 degrees. The wide spectral range of 400-1100nm makes it suitable for physics and optical laboratories, as well as checking thermal window efficiency. This feature-rich tester simplifies data collection with built-in data logging for up to 99 readings. It also includes min/max/avg memory and a data hold function to capture specific values. For field researchers, the ability to mount the unit on a tripod and the inclusion of a time setting function allow for consistent, long-term solar transmission measurements.
