School Savers - Vernier PYR-BTA Pyranometer

Vernier PYR-BTA Pyranometer

The Pyranometer measures the power of electromagnetic radiation. It is sensitive to near infrared, visible, and UV radiation, where 90% of solar energy is concentrated. It reads in watts per square meter, so it is great for experiments with solar cells and calculating their efficiency.
It is weatherproof and has a dome-shape top to allow it to handle a wide range of sun angles. It comes with a 6 meter cord.
