It supports data logging of up to 99 readings with min/max/average memory, includes a tripod mount, batteries, and carrying case, making it an essential precision tool for professionals and DIYers seeking reliable solar power data. ## 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.
