Product Overview
MODEL 4000 Dissolved Hydrogen Sensor in Water is based on Pd alloy thin-film hydrogen detection technology. The sensor chip can be directly immersed in water without the need to separate hydrogen from water. This technology features absolute hydrogen specificity and no cross-response to other flammable gases. Meanwhile, the sensor chip of MODEL 4000 adopts a Pd alloy-oxide semiconductor field-effect transistor (MODFET) structure, combined with high-sensitivity Pd alloy doping & thin-film preparation technology, and PTFE composite insulating thin-film preparation technology, allowing MODEL 4000 hydrogen sensor achieves superior long-term stability and eliminates the need for period maintenance.
