Mettler Toledo Process Analytics Division has introduced Thornton model 6510i dissolved ozone sensor with Intelligent Sensor Management (ISM) for continuous, fast, and reliable monitoring of dissolved ozone in pharmaceutical waters. ISM features enable the user to maximize lifetime of the sensor and minimize downtime to perform routine maintenance.

Typical applications include monitoring dissolved ozone in active pharmaceutical ingredients (API), Water for Injection (WFI), Pure Water (PW), High Purity Water (HPW), and vaccines.

According to product manager Christie Martin, “Ozone is an effective sanitizer for pharmaceutical applications, and the new Thornton 6510i ozone sensor utilizes the full spectrum of ISM capabilities to optimize ozone measurement.”

A number of ISM's benefits make the 6510i ozone sensor a particularly easy to use instrument: The Dynamic Lifetime Indicator predicts when the sensor's inner body and membrane will need to be replaced. To ensure the sensor's measurement accuracy will always be high, the Adaptive Calibration Timer informs operators as to when the sensor should be calibrated. The in-built sanitization counter allows the limit of ozone concentration and duration of sanitization cycle to be defined by the user on the connected transmitter.

The 6510i ozone sensor with ISM may be used with Thornton M300ISM or M800 multi-parameter transmitters, which enable the use of two or four digital sensor inputs for continuous measurement of ozone, dissolved oxygen, conductivity, pH, and total organic carbon.

Mettler Toledo Process Analytics Division develops and manufactures instruments and sensors used for liquid process measurement and control in pure and ultrapure water applications, offering measurements of resistivity/conductivity, pH, dissolved oxygen, dissolved ozone, oxidation reduction potential (ORP), total organic carbon (TOC) and flow.
