2scan HY-ALERTA™ 500 Handheld Hydrogen Leak Detector The hydrogen-specific HY-ALERTA™ 500 is ideal for rapidly detecting and locating hydrogen leaks from 15 ppm to 100% in air or inert gases. The leak detector uses an easy-to-see LED array on the probe to help quickly and confidently identify the source of a leak. An LCD on the controller provides the numeric value or range of the amount of hydrogen detected. A flexible cable lets the user move the sensor probe to virtually any potential leak source. How it Works A thin film palladium-nickel alloy absorbs and desorbs hydrogen as it comes in contact with the sensor. The palladium catalyzes the hydrogen molecule into atomic hydrogen, which gets absorbed into the metal lattice and changes the bulk resistivity or charge density. This change is calculated very accurately and reported in real time. The sensor is hydrogen specific because even though palladium can catalyze several elements, only hydrogen can penetrate the lattice structure of the sensor at a rate that is meaningful to the measurement. As a result it is unaffected by most other gases. Since it is a solid state device, the sensor does not degrade over time. Ease of Use With no moving parts, the leak detector is extremely reliable and easy to use. It typically only requires a quick periodic bump test every three months, with a full factory calibration recommended annually. A verification kit is available from H2scan. No other maintenance is necessary. Performance and Safety The model 500 handheld leak detector is intended for use in an air, oxygen, or inert gas environment where hydrogen is only occasionally present for short periods, as may occur if there a leak is suspected. The model 500 is UL and CE approved for safe operation.
