AquaMS - Dissolved Hydrogen Measurement Submersible Probes
FromAquaMS
Dihydrogen is found especially in waste waters and industrial waters. H2 is used in many chemical reactions and knowing its concentration allows to optimize products synthesis. In situ measurement of this specific parameter avoid any modification risks of the water quality often caused when a sample is taken.

Dissolved H2 measurement can be done with 2 probes type:
- The MS08 device for a portable or laboratory measurement. This kit is composed by a data reading box and 2 linked probes. The titanium probe contains the H2 amperometric micro-sensor and the other probe is a temperature sensor.
- The CTD48 system for an online application in the environment. This probes integrate several sensors in the head. The titanium protection cage contains the H2 amperometric micro-sensor, a pH sensor and a temperature sensor. It can also be completed by a pressure sensor. Measurement data are operated by the embedded electronic in the probe’s body. A CTD48M version is also available for the data recording.
- Sewage networks protection
- Industrial process conduct
- Staff protection before intervention
- Laboratory measurement
Dissolved H2 passes through a membrane only pervious to gases. It spreads to reach the working electrode where an electrochemical oxidation reaction happens. The generated current is proportional to the H2 concentration. This current from 0 to 400 pico-amperes is translated in 0-5 V by the probe electronic.
