Hydrogen concentration
H2SCAN instruments allow direct monitoring of hydrogen without interference. They use a
palladium-nickel sensor, protected by a number of patents.
These compact analyzers allow the selective measurement of H2 concentrations in the range of 0.1-
100%. In addition to monitoring technology, they also enable the safe detection of hydrogen leaks.
They are available in various portable and stationary versions and are much more user-friendly than
indirect thermal-conductivity or chromatographic devices.
Impurities in hydrogen
V&F’s HydrogenSense analyzer is designed to monitor trace
pollutants in hydrogen in accordance with ISO 14687: 2019 and SAE
J2719_2020, which define the maximum permissible concentration of
pollutants in hydrogen.
These pollutants include in particular H2O, O2, He, N2, Ar, CO, CO2,
TS THC, HCHO, HCOOH, NH3, HCl a Cl2. The instruments work on
the principle of mass spectrometry and allow a single analyzer to
monitor all components with a very fast response.
Clamp-on flowmeters Flexim allow accurate measurement of
hydrogen flow from the outside of the pipeline. This is a particularly
advantageous solution to the problem of tightness of the joints in
hydrogen technologies.
