HY-ALERTA™ 500 Handheld Hydrogen Leak Detector

H2scan recognizes the importance of detecting and locating hydrogen leaks as quickly as possible.  H2scan’s HY-ALERTA™ 500 Handheld Hydrogen Leak Detector is the industry’s most versatile, portable hydrogen leak detector able to respond to the widest range of hydrogen gas concentrations without the need of any peripheral equipment.  The hydrogen sensor probe has a unique visual LED array that will effectively help navigate to the source of a hydrogen leak where hydrogen gas is produced, used, transported, or stored.

With two sensing elements on the same semiconductor die, the HY-ALERTA™ 500 can detect hydrogen leaks as low as 15 ppm and will not saturate or be destroyed when detecting high concentrations of hydrogen up to 100%.  The flexible cable allows the sensor probe access to virtually all potential leak sources. Some applications where this product and its benefits have been demonstrated are in Dry Cask Welding in Nuclear Facilities and in the measurement of hydrogen in a Hydrogen-cooled generator.
