dissolved hydrogen meter
a handheld, portable dissolved hydrogen meter
The determination of the total dissolved hydrogen is one of the most important parameters for the analysis in power plants, wastewater and in industry.
On the other hand, the total dissolved hydrogen concentration is an interesting parameter for scientists of several scientific departments. They use this parameter to understand chemical reactions and to optimise the process of the industrial production of chemicals.
But due to a lot of the hydrogen’s inconvenient chemical properties, like high chemical reactivity, possible storage in metals and the fast concentration exchange between the liquid sample and the gaseous phase above (mostly air), the determination is difficult. Even though the sampling and the determination have been done very carefully, the results are uncertain and mostly disappointing.
All these disadvantages could be avoided if the new Submersible Hydrogen Probe System is used for the accurate and reliable in-situ determination in depths of up to 100 m or in case of pressures of up to 10 bar.
The “heart” of this new probe is the hydrogen micro-sensor, which allows a very fast measurement with a very high local concentration resolution. For details, please read the “general information for the hydrogen micro-sensor”.
