AquaMS - Dissolved H2S and Sulphides Measurements Submersible Probe
The determination of dissolved H2S concentration and total dissolved sulphide amount (TDSA) is necessary for the optimization of reagent injection in sewage network et for the conduct of industrial process. On the other hand, H2S is involved in corrosion phenomenon of networks and cause bad smells. The H2S amperometric micro-sensor allow to measure this parameter directly in water without sampling, avoiding then every risks of sample oxidization.
Dissolved H2S and TDSA measurement can be done with two probes type:
- The MS08 device, for portable or laboratory measurement: this kit contains a reading data box and two probes are linked to it. The titanium probe contains the H2S amperometric micro-sensor and the other probe combine a pH sensor and a temperature measurement, necessary for the concentration determination.
- The CTD48 system, stronger, for a continuous use in water: the probe contains in the head several sensors that allow concentration calculation. The titanium protection cage includes then a H2S amperometric micro-sensor, a pH sensor, a temperature sensor and can also hold a pressure sensor. Measurement data are operated through electronic embedded in the probe’s body. A CTD48M version that records data is also available.
- Waste water networks protection and monitoring
- Optimization of reagent injection
- Conduct of industrial process
- Staff protection before intervention
- Laboratory measurement
H2S passes through the membrane pervious to gases and get inside the sensor where a redox catalyst is placed. The reaction between the catalyst and H2S give a product that is oxidized at the working electrode. The oxidation leads to the creation of an electrical current with an intensity proportional to H2S concentration. TDSA measurement is made thanks to the simultaneous measurement of pH and temperature..
