EXA GD402/GD40 Hydrogen Purity Monitor
The EXA-based GD402/GED40 hydrogen purity monitor is a fast, accurate and reliable process gas measurement device that is unaffected by ambient temperature or vibration and does not require reference gases or a controlled temperature environment. It consists of a gas detector (GD40) and a signal converter (GD402) that fit directly into most generator stations. This monitor’s low maintenance design, self-diagnostic capabilities and easy to use programming provide a broad range of control options to meet the demanding environments of power producers.
120HD PORTABLE HYDROGEN ANALYZER
The 120HD analyzer functions as a katharometer. It operates by having two parallel tubes that both contain gas and heating coils. The gases are examined by comparing the rate of loss of heat from the heating coils into the gas.
