An all in one unit for measuring trace impurities(ppb/ppm) N2-Ar-HeO2-CH4-CO-CO2- NMHC-sulfurs-formaldehyde-ammonia-halogenated-formic acid and water in hydrogen. The unit is capable of meeting the ultra-high purity requirements for hydrogen used in fuel cells as set out in ISO 14687.

The HyDetek system uses a combination of LDetek’s plasma emission detector, thermal conductivity detector and a quartz crystal moisture sensor to measure all critical impurities. It is suitable for use in electrolysis systems producing green hydrogen as well as steam methane reforming processes and grey hydrogen.


  • CE in compliance with EMC directive 2004/108/EC, EN 61000-6-2:2005 for immunity & EN 61000-6-4:2007 for emissions
  • IECEx : Ex pxb IIB+H2 T4 Gb (with MultiDetek-Ex-solution)
  • ATEX : II 2 G Ex pxb IIB+H2 T4 Gb (with Multidetek-Ex-solution)
