Product Information

The Rapidox 7100 Green H2 Production Analyser can be used in a
laboratory or on-site to analyse the output of your hydrogen production
process. Using a combination of Thermal Conductivity (TCD), and
Electrochemical (EC) sensors with the option of including Ceramic
Moisture (DP) sensor technology, the Rapidox 7100 offers accurate
analysis that can be relied upon.
The analyser will measure the gas composition providing % or ppm values
for Hydrogen (H2) and Oxygen (O2) as well the Water (H2O) content
generated. With our bespoke design of the analyser, we can include a range
of other sensors also if your production methods have any other gases
which require monitoring. Our customer designed firmware for the analyser
will also calculate and record the Gross Calorific Value (GCV) of the gas
throughout the measurement.
The Rapidox 7100 Green Hydrogen Analyser is available as either a
benchtop version for the laboratory or in a 19″ rack mountable case
which can be housed in a suitable enclosure for use in an external or
hazardous area. The Rapidox 7100 Green Hydrogen Analyser is
highly configurable to suit individual H2 production requirements.
