New Dissolved Ozone Sensors Introduced For Pharmaceutical And Semiconductor Water Sanitization


Mettler-Toledo Thornton introduces new dissolved ozone sensors for reliably monitoring pure water sanitization. Ozone, the tri-atomic form of oxygen (O3), is used increasingly in pharmaceutical, semiconductor, bottled water and beverage systems where Mettler-Toledo Thornton already provides measurements of many other parameters. Now the same instruments can be used to assure that full sanitization has been accomplished and that residual ozone has been eliminated afterwards.

Competence in multiparameter instrumenting
Mettler-Toledo Thornton is in a unique position to provide high value and performance in ozone measurement. The products combine decades of innovation in polarographic sensor technology of the Process Analytics division with THORNTON's extensive transmitter capabilities. The result is a product line that seamlessly integrates ozone measurement into multiparameter instrumentation specifically designed for monitoring pure water treatment systems.

The new ozone sensors connect to the widely used Thornton 770MAX instruments that can also measure conductivity, spec. resistivity, TOC, dissolved oxygen, flowrate, pH, ORP, temperature, tank level and/or pressure. Availability of up to 6 channels of mix-and-match parameters, now including ozone, in the 770MAX reduces the cost and complexity of pure water monitoring and treatment systems. Where fewer measurements are needed, the ozone sensor may also be used with the 2-channel Thornton 2000 instrument.

High Performance / low maintenance
The ozone sensor provides reliable and accurate response at typical sanitization levels as well as the near-zero levels after ozone destruct stages of treatment. The multi-channel capability allows it to be used economically for the multiple measurement points of many treatment systems.

The ozone sensor requires only infrequent, simple maintenance, with a drop-in membrane cartridge design that can be changed in a few minutes and at very nominal cost. The maintenance interval is typically only once a year.
