EKO Instruments ML-01 Si Pyranometer
The compact, industrial-grade ML-01 silicon pyranometer is made for high-quality irradiance measurements. ISO 9060:2018 Class C, fast response, light but tough, the ML-01 features a mono-silicon detector with a UV-resistant cone-shaped diffuser that helps to minimise soiling and water deposition, delivering an excellent cosine response, even at low solar elevation angles.
