Solar Power Meter for Radiation Energy Measurement (BTU/(ft2*h) / W/m2)

The Solar Power Meter is a highly precise device designed to measure the power per unit area of incident solar radiation. Equipped with a high-precision light sensor, it provides accurate and fast measurements with just a simple power-on, making it one of the best easy-to-read handheld meters. This device is ideal for measuring the solar characteristics of glass, film, or other transparent materials.
