Peracetic Acid Sensor

Electrochemical sensors are a widely used sensor for work place gas monitoring.

Peracetic acid sensor. Peracetic acid diffuses into the sensor through the back of the porous membrane to the working electrode where it is oxidized or reduced. Peracetic acid sensor paa 1 ma. Peracetic acid cas no. 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.

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. The pa80 peracetic acid analyzer features a plug and play design that incorporates a flow control device a ph sensor a peracetic acid sensor and the t80 transmitter that are conveniently mounted on a pvc panel. Peracetic acid sensors are amperometric devices isolated from the water by a permeable membrane. Connect the sample and drain lines connect the power and outputs and it is ready to use.

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. We offer sensors in varying ranges of concentration for free chlorine bromine total chlorine chlorine dioxide ozone peracetic acid and hydrogen peroxide. It is a strong oxidant and is highly reactive. This electrochemical reaction results in an electric current that passes through the external circuit.

The net effect is that the sensor generates a current proportional to paa concentration. Peracetic acid has also previously been used during the manufacture of chemical. Peracetic acid measurement peracetic acid is used mainly in the food and beverage industries but also in the cosmetic sector pharmaceutical industry and medical sciences for disinfection purposes. Continuous measurement and control of peracetic acid is required when there are high requirements to disinfection and quality assurance.

Sensor for the measurement of peracetic acid without. 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. It is a colorless liquid that has a strong vinegar like odor that can be smelt at very low levels.
