New Dissolved Ozone Sensor

Mettler Toledo, under the Thornton brand, has released a dissolved ozone sensor employing the company's Intelligent Sensor Management technology that helps to streamline the use of sensors for measuring pH, conductivity, dissolved oxygen or ozone, and a host of other aspects of pure water. The pureO3 sensor technology provides rapid response in a sensor assembly with a built in digital measuring circuit and Intelligent Sensor Management (ISM®). The pureO3 is designed for monitoring low concentrations of dissolved ozone in semiconductor and pharmaceutical pure water samples, bottled water and similar applications. Minimal maintenance requirements and reliable long-term operation are hallmarks of this sensor.

How it works, in the company's own words...

"The pureO3 sensor uses a gas permeable membrane to separate the sample from the electrochemical cell inside. Ozone diffuses through the membrane in direct proportion to the partial pressure of ozone outside the sensor.The cathode and anode inside the sensor are polarized with a voltage to enable the electrochemical reaction of ozone. Ozone is reduced at the cathode while the anode is oxidized, producing a current in direct proportion to the amount of ozone present. The very low current developed by these sensors allows them to have a long life with low maintenance. An embedded temperature sensor enables temperature compensation to adjust for the changing permeability of
the membrane with temperature. In addition, the instrument uses the temperature value to convert the ozone partial pressure signal to a dissolved ozone concentration value by compensating for the changing solubility of ozone with temperature."

Benefits to the user from the ISM® based sensor.

• Full sensor identification by type and serial number.
• Calibration history with actual calibration, factory calibration, and last three calibration.
• Programmable timer to facilitate maintenance planning, reducing downtime.
• Starting calibration interval of 90 days.
• Time to maintenance function integrates ozone concentration over time, indicating replacement time for membrane body and electrolyte.
• Dynamic Lifetime Indicator for inner body used ozone concentration integration to predict life of inner body and membrane. Starting values, membrane body lifetime 180 days, inner body 1080 days.
• Sanitization counter allows the limit of ozone concentration and duration of sanitization cycleto be defined on the transmitter.

The pureO3 sensor with ISM operates with the M800 and M300 transmitters. ISM features enable users to maximize the lifetime of the sensors and minimize downtime by predicting when sensor maintenance is required.

Gas phase oxygen measurement is used industrially for process safety and the prevention of oxidation. The ability to obtain oxygen level readings in real time can be advantageous in both application classes. While numerous measurement methods are available, Ingold (Mettler Toledo) provides a rugged and robust solution in their direct insertion sensors. Some measurement systems require gas sampling or conditioning, but the Ingold sensor is inserted directly into the process to provide fast and accurate oxygen readings. Coupling the direct insertion feature with Ingold's Intelligent Sensor Management delivers fast and direct O2 measurements with minimized maintenance, no sampling or conditioning, and limited downtime.

Continuous Microbial Monitoring For Pharmaceutical Waters

Monitoring process water microbial counts in the pharmaceutical industry has traditionally been a time consuming, hands-on operation. Sample preparation, plate counting, stains, reagents, and the time required to get results has kept microbial monitoring a cumbersome task that provides only snapshots of the process water quality at the time of sampling.

Mettler Toledo has introduced its Model 7000RMS, a continuous on-line microbial monitoring system for purified water and water for injection. The system uses advanced laser based technology to provide immediate detection and quantification of microorganisms. Particles as small as .52 microns can be detected, and the monitor uses recent advancements in spectroscopic technology to differentiate between microbial and inert particles.

The 7000RMS puts on-line analytics for microbial contamination on the same timeline as TOC and conductivity, with all three critical aspects now subject to real time measurement.

The white paper included below delivers a deeper and more detailed view of the technology and the how the system works. Detailed application and product information is available from product specialists.

Innovative Tunable Diode Laser TDL Gas Analyzer

Mettler Toledo has developed the first compact TDL with an insertion probe form factor. The instrument requires only a single flange or insertion point in process piping. Several versions are available that accommodate a range of pipeline and media conditions. The video below tells the whole story. Detailed application information is available from product specialists.

New Generation of Mettler Toledo M300 pH/ORP, Dissolved Oxygen, Conductivity, & Ozone Transmitters

M300 Process Transmitter

METTLER TOLEDO Process Analytics has released a second generation of M300 transmitters for pH, Conductivity, Oxygen, and Ozone sensors in April 2016. This release simplifies both the Process and Water M300 portfolio through the reduction of 26 unique model numbers down to ten. This is possible through new mix-mode functionality providing compatibility of both analog and digital Intelligent Sensors Management (ISM®) sensors to the latest generation. New M300 transmitters are easily identified by their high-contrast touchscreen display and advanced ISM diagnostic capabilities providing significant advantages to the product line.

The multi-parameter M300Process transmitter line for pH/ORP, dissolved oxygen, conductivity and ozone measurements offers exceptional measurement performance as well as excellent user ergonomics.

The high contrast black and white touchscreen together with the harmonized menu structure for all parameters, facilitates navigation and ensures easy and user friendly operation.

On-line diagnostics information allows you to schedule sensor maintenance or replacement. The clearly visible diagnostic information lets you know when it’s time to do maintenance or calibration of sensors equipped with Intelligent Sensor Management (ISM) technology.

The integrated USB interface allows you to use it for data logging or to store the configuration on a USB stick.

Second generation M300 transmitters are direct replacements to first generation products.
