Solar Power Meter, 2000 W/m² Range Handheld Solar Irradiance Meter with Dual Units, MAX/MIN Tracking, Data Hold, Manual Zeroing, Digital Sun Meter for Solar Panel Evaluation and Site Testing

✔ 【Wide Measuring Range】The measurement range of our digital solar power meter is 0-1999 W/m² and 0-634 BTU, with an accuracy of ±10 W/m² and ±3 BTU/(ft²·h). ✔ 【Dual Units Switching】The solar irradiance meter features W/m² and BTU/(ft²·h) unit switching to match different testing requirements. Making results easier to compare across solar-energy and heat-radiation applications. ✔ 【MAX/MIN Tracking】The irradiance meter records maximum and minimum measurement values with button controls. This function helps users observe changes in sunlight intensity without continuously watching the display ✔ 【Ranging Scale Selection】This sun meter allows manual selection of 199.9 or 1999 W/m² scale, providing users direct control over the displayed resolution when measuring weak or strong sunlight conditions. ✔ 【Manual Zeroing】The solar radiation meter features easy zero-adjustment control. Use it before measurement to establish the correct starting point. The clear digital display also supports straightforward operation when testing.
