A key advantage of this model is the built-in RS-485 communication port, which enables remote data reading and integration with Smart Home systems or Building Management Systems (BMS). The meter is characterized by exceptional measurement precision (accuracy class 0.001 kWh) and a wide current range, supporting a base current of 5A and a maximum current of up to 100A.
The device is equipped with a clear, blue-backlit LCD display (5+2 digits), which ensures excellent visibility of parameters even in total darkness. Additional LED signaling informs about device operation and pulse generation. A solid housing made of high-quality plastic with an IP51 protection rating guarantees durability and resistance to external factors. The product is fully compliant with European standards EN50470-1:2006 and EN50470-3:2006, which confirms its highest quality and safety of use. By choosing an ORNO meter, you gain full control over energy expenses and the ability to optimize its consumption, which translates into real financial savings and care for the environment.
