Digital Solar Power Meter

Since 1910, General Tools has grown to become the recognized industry leader for specialty hand tools and instruments. This digital solar power meter 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.”,”highlights”:[“Measures solar power intensity in units of W/m2 or Btu/(ft2 x h)”,”Uses a silicon photodiode and cosine angular correction”,”Min/max/avg memory, wide spectral range, stores 99 readings”
