Featuring a wide spectral range sensor (400-1100nm) with cosine correction, it measures solar power intensity up to 2000 W/m² or 634 BTU/(ft²·h) with 10 W/m² accuracy. Its 4-digit LCD updates readings 4 times per second and supports data logging of 99 entries with min/max/average memory. Powered by included AA batteries and equipped with tripod mounting, it’s ideal for solar research, meteorology, agriculture, and energy efficiency testing. ## Description General Tools DBTU1300 digital solar power meter can measure the solar power radiated from any direction, angle or position, can be mounted on a tripod and it has a time setting function. It measures solar power in units of watts per square meter or Btu/(ft2 x h) and displays readings on a large 4-digit LCD. It is ideal for checking thermal window efficiency and has applications in meteorology, agriculture, solar radiation measurement, solar power research, physics and optical laboratories and solar transmission measurement. The feature rich tester is designed with a broad spectral range and is cosine corrected ( SPECIFICATIONS Measurement range: 0 to 2000 W/m2 or 0 to 634 Btu/(ft2 x h) Measurement accuracy: 10 W/m2 ( 3 Btu/(ft2 x h)) or 5% of reading, whichever is greater Measurement resolution: 0. 1 W/m2 or Btu/(ft2 x h) Spectral range: 400 to 1000nm Sampling rate: 4x per second Auto power off: After 10 minutes of inactivity (can be disabled) Operating temperature: 32° to 122°F (0° to 50°C) @ Weight: 5. 6 oz. (158g) Power source: Four "AA" batteries (included) provide approximately 100 hours of operation. ## Features - MEASURES: Displays solar power intensity from 0 to 2000 W/M2 or 0 to 634 BTU/(ft2 x H). - END MOUNTED: Extremely stable light sensor with a wide spectral range (400-1100nm) and a sampling rate of 4 times/second. - COSINE CORRECTED: Uses a silicon photodiode and cosine Angular correction (<5% for angles < 60°) to measure the solar power radiated from any direction, angle or position. - FEATURE RICH: Current time setting, automatic transmission of measurements and data logging of up to 99 readings, as well as min/max/Avg memory + data Hold and auto power off (can be disabled). - GENERAL TOOLS: We're a recognized leader in designing and developing specialized precision tools dedicated to delivering exceptional customer service.
