Solar Power Meter, Solar Irradiance Meter Data Retention Sun Light Energy Measuring Tester with W/m² and Btu Units, ABS Material for Meteorology Research, Physics and Optics Experi

【Precision Measurement】--- The professional-grade solar irradiance meter provides ±5% accuracy for measuring 0-2000W/m² or 0-634Btu intensity. Ideal for solar panel installers, renewable energy consultants, and meteorology researchers to quantify sunlight exposure in solar farms, greenhouses, and outdoor research stations.

【Smart Data Features】--- Utilize the HOLD function to freeze readings during field measurements and MAX mode to automatically track peak solar intensity. Particularly useful for comparative analysis of daylight variations in architectural planning and agricultural light studies.

【Plug-and-Play Operation】--- Provides instant measurements without calibration through the auto- sensor. The 2.5x sampling rate ensures reliable data collection for solar water heater efficiency tests and photovoltaic system maintenance across multiple seasons.

【Dual-Unit Flexibility】--- Switch seamlessly between W/m² for scientific reports and Btu for HVAC system compatibility. Essential for solar product engineers adapting to international standards or educators demonstrating energy conversion principles in physics labs.

【Durable Field Companion】--- The IP54-rated ABS housing withstands occasional rain/dust exposure during rooftop measurements. Compact 158g design with anti-slip grip facilitates prolonged use in solar site surveys and portable UV index monitoring applications.
