EKO ML-02 Si-Pyranometer:

The EKO ML-02 silicon pyranometer delivers accurate irradiance measurements. Its compact and industrial-grade design, certification according to ISO 9060:2018 Class C, and fast response time make it a reliable and durable choice.

A mono-silicon detector with a UV-resistant cone-shaped diffuser minimizes soiling and water deposition. This ensures excellent cosine response even at low solar elevation angles. Made in Japan and manufactured to EKO’s strict quality standards, the device comes with a 2-year warranty and a 2-year recommended recalibration interval. It also has unique calibration that complies with international standards, making it cost-effective.

Designed for meteorological, agricultural, and environmental applications, the ML-02’s small size, high accuracy, and quality construction make it versatile. Various mounting accessories allow for use on drones, solar-powered vehicles, building exteriors, and more.

Furthermore, the device can be combined with a POA bracket, M-box (Modbus®), and PT-100 temperature sensor for cost-effective PV rooftop monitoring. It’s a great choice for anyone in need of high-quality irradiance measurements.
