Description
The sensor is built on a fuel cell behind a gas-permeable membrane. It measures the combined gas (H₂, CO, C₂H₂, C₂H₄) or hydrogen alone. Accuracy is ±10% of reading ±25 ppm, and for moisture ±2% RH. Communication is over Modbus and DNP 3.0, with optional IEC 61850. Operating temperature −40…+55 °C, packaged weight 9 kg. The previous generation, Hydran M2, works as a single-component DGA monitor.
