The compact, industrial-grade ML-01 silicon (ML-01 Si) pyranometer (MTI.AWS.EK.01) is made for high-quality irradiance measurements. ISO 9060:2018 Class C, fast response, light but tough, the ML-01 and its smaller sister sensor, the ML-02, both feature a monosilicon 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. Made in Japan and manufactured to EKO’s strict quality standards, the ML-01 and ML-02 are compliant with international standards, offering a cost-effective alternative to larger thermopile-based sensors that is easy to integrate into any project or application. The ML-02 can also be combined with the M-box (Modbus®) Signal Converter and PT-100 temperature sensor to build a cost-effective PV rooftop monitoring system.
