ATI’s Model Q46D Dissolved Oxygen Monitor is designed to provide reliable oxygen measurement and help reduce operating costs. Two types of sensing technologies are available for use with the Q46D system: Membraned Electrochemical and Optical (fluorescence). Both sensors will provide reliable longterm performance with minimal maintenance.
Commercial sensors to monitor dissolved CO2 and H2S in seawater are so far unavailable. Therefore a sensor device based on commercially available sensors for gas monitoring was designed, constructed, and tested. The sensor array was tested in the submarine hydrothermal system of Panarea, Aeolian Islands, Italy. The first application provided important insight into variations of CO2 and H2S ...
Unisense supply intelligent sensor solutions for direct and realtime monitoring of dissolved H2S and N2O in wastewater applications. The SulfiLogger™ sensor measures H2S directly in raw wastewater in sewer networks, while the Unisense Environment sensor system monitors dissolved N2O at wastewater treatment plants.
The dissolved sulphide monitor allows the ability to measure sulphides in solution by utilising a polarographic H2S gas sensor that is isolated from the sample. This results in a system that operates continuously on many types of water wastewater stream, with little adjustment required and minimal maintenance. General issues and standard method:
Special Wet H2S Sensors: The system utilises a special sensor designed to operate in condensing gas streams without the water vapour blinding typical of standard sulfide sensors. Technical Specifications: Gas Type: Hydrogen Sulfide. Sensor Type: Special wet gas sensor design. Display: PPM, PPM, PPM (programmable)

· S sensor technologies include metal oxide sensors, sometimes called solid ceramicmetallic (cermet) film devices, and electrochemical cells. Each of these devices depends on the migration of H 2 S from its source to the sensor and can be incorporated into a fixedpoint detection system or carried by the individual.
The sensor signal is generated by reoxidation of ferrocyanide at the anode in the tip of the sensor (Jeroschewski et al. 1996). The internal guard electrode facilitates a constant ratio of ferri to ferrocyanide in the electrolyte, thus minimizing the zerocurrent. The ferri/ferrocyanide complex is light sensitive and the sensors are painted black to minimize light interference.

ATI’s Model A15/81 Dissolved Sulfide Monitor provides an improved method for measuring sulfides in solution. Rather than using an SIE sensor, the A15/81 employs a polarographic hydrogen sulfide (H2S) gas sensor that is isolated from the sample.
Not affected by CO2 or H2S; One year limited warranty ; This is a replacement for the Aquametrix AMODO Dissolved Oxygen Sensor Description. The AquaMetrix AMODO2 optical dissolved oxygen sensor outputs a direct analog (420 mA) signal that can be set for percentsaturation or concentration (mg/l or ppm) or both. It can connect to the AquaMetrix AM2300 controller, AM2252 controller or a …
· dissolved hydrogen sulfide sensor details This amperometric H 2 S microsensor for shallow water has been developed for the in situ determination of dissolved H 2 S/Sulfide in natural waters. Because of the partial pressure of the gaseous H 2 S, the analyte is separated by permeation through the membrane.
Dissolved H 2 S 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 H 2 S amperometric microsensor and the other probe combine a pH sensor and a temperature measurement, necessary for the concentration determination.

insitu determination of dissolved H2S/Sulphide in natural waters. Because of the partial pressure of the gaseous H2S, the analyte is separated by permeation through the membrane. Inside the sensor the hydrogen sulphide reacts with a redox mediator. The reoxidation at the working electrode causes a current corresponding to the concentration of the dissolved molecular H2S amount. The sensor has ...
The integrated H2S micro sensor is the biggest innovation of this system, it allows a fast measurement with a very high local resolution. The multiparameter MS08 system collects raw H2S data and temperature information to perform compensation calculations and display dissol ved H2S concentration in mg/l.
