Rapidox - Model 7100 Blue -Hydrogen Analyser

The Rapidox 7100 Blue Hydrogen Analyser can be used in a laboratory or onsite to analyse the output of your hydrogen production process. Using a combination of Thermal Conductivity (TCD), Infra-Red (IR), Tuneable Laser Diode (TLD) and Electrochemical (EC) sensor technology, the Rapidox 7100 offers an accurate analysis that can be relied upon.

The analyser will measure the gas composition by providing % or ppm values for Hydrogen (H2), Methane (CH4), Carbon Dioxide (CO2), Carbon Monoxide (CO) and Oxygen (O2). It also has an optional upgrade to include a dewpoint sensor to measure the moisture content in the gas sample. With our bespoke design of the analyser, we can include a range of other sensors if your production methods have any other gases that 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 Blue 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 Blue H2 Analyser is highly configurable to suit individual H2 production requirements.
