Peracetic Acid Sensor

Sensor for the measurement of peracetic acid without.

Peracetic acid sensor.

This electrochemical reaction results in an electric current that passes through the external circuit. As paa diffuses through this membrane it comes in contact with an active electrode and is reduced on the surface. The net effect is that the sensor generates a current proportional to paa concentration. Peracetic acid also known as peroxyacetic acid or paa is an organic chemical compound that is used in a mixture with acetic acid and hydrogen peroxide in water.

Peracetic acid has also previously been used during the manufacture of chemical. 79 21 0 also known as peroxyacetic acid or paa is an organic chemical compound used in numerous applications including chemical disinfectant in healthcare sanitizer in the food industry and disinfectant during water treatment. Peracetic acid diffuses into the sensor through the back of the porous membrane to the working electrode where it is oxidized or reduced. Electrochemical sensors are a widely used sensor for work place gas monitoring.

Chemdaq developed a proprietary chemical filter that allows the peracetic acid to pass through but selectively removes essentially all of the hydrogen peroxide from the gas stream. It is a colorless liquid that has a strong vinegar like odor that can be smelt at very low levels. Both peracetic acid and hydrogen peroxide are strong oxidizing agents and so there is some cross sensitivity of hydrogen peroxide on the peracetic acid sensor. Peracetic acid sensor paa 1 ma.

Continuous measurement and control of peracetic acid is required when there are high requirements to disinfection and quality assurance. Peracetic acid cas no. Connect the sample and drain lines connect the power and outputs and it is ready to use. We offer sensors in varying ranges of concentration for free chlorine bromine total chlorine chlorine dioxide ozone peracetic acid and hydrogen peroxide.

Whether the application is a cooling tower food and beverage drinking water wastewater or swimming pool these sensors are the ideal solution. It is a strong oxidant and is highly reactive. The perasense peracetic acid sensors which give a peracetic acid measurement in ppm or mg l and a range of flow cells are available with different peracetic acid controllers giving you the same great performance with different communication display and control options.
