"We have had excellent success with Pi's Ozone Analysers" Kahraman Kalyoncu, Turkey

OzoSense Residual Ozone Analyzer from PI for the measurement of ozone concentration in water, is designed to be simple to install and operate and offers unrivalled stability, accuracy and precision, while offering excellent value for money.

The OzoSense range of Ozone Analyzers, Ozone Controllers and Ozone Monitors utilise the very latest and best ozone sensors available in the world today. They are membrane devices which are insensitive to changing pH, use no reagents, are extremely stable, and have reduced maintenance and reduced whole life costs.

New! Now available with up to four ozone sensor inputs.

Residual Ozone Analyser Key Benefits

  • Stable and reliable - excellent process control
  • Suitable for all potable, process and salt waters
  • Up to 6 months between maintenance
  • Up to 3 months between calibration
  • Does not respond to residual chlorine
  • Resistant to detergents in the water

The OzoSense sensors and flow cells are available with different controllers giving you the same great performance with different communication, display, and control options. With the OzoSense range of residual ozone analyzers, you get everything that you need - and nothing that you don't, saving money without compromising the quality of measurement.

The OzoSense Residual Ozone Monitor suffers no interference from other oxidants such as Chlorine. Coupled with its excellent zero and calibration stability it is extremely well suited to the monitoring of the Residual or Dissolved ozone concentration in water in clean or harsh environments.

The Residual O3 Monitor is bufferless and reagent free, meaning it has a low total cost of ownership and with maintenance intervals at 3 or even 6 months, the bufferless Ozone Monitor is fast becoming the instrument of choice for the engineer who wants the best ozone monitor at the best price.

Autoflush

As described in a seperate brochure, the OzoSense can come equipped to automatically clean itself at user defined intervals with all the benefits of no operator intervention for 6 months. The Autoflush is particularly useful in food preparation, pulp and paper, and many applications where there is likely to be a build up of solids in the sample.

Principle of Operation

The membraned amperometric ozone sensors are two electrode sensors which operates at an elevated applied potential which in turn eliminates zero drift. Its unique design means that no reagents or buffers are required at all.

In addition to the state of the art amperometric chlorine dioxide sensors the OzoSense range of ozone analyzers has all the functionality that you need, and more. Simply choose the CRONOS, CRIUS® or CRATOS controller to give you the highest quality ozone monitor, with all the functionality you need, at the lowest price possible. This means that you pay for everything that you need and nothing you don't, without sacrificing the quality of measurement.

OzoSense Water Treatment Applications

  • Ozone Dosing Control
  • Remote Sites
  • Cooling Towers
  • Food Preparation
  • Hospitals
  • Secondary Ozonation

Anywhere you have a requirement to measure residual ozone is a suitable application for the OzoSense. The OzoSense ozone monitor range is particularly suited to working in sites where reliability and ease of use are most important. The sensor is resistant to the presence of tensides making it suitable for use in many washing applications.

Multi-Sensor Systems

The whole range of OzoSense Ozone Monitors and Controllers can be fitted with additional sensors such as more ozone sensors, chlorine, pH and many others. Please ask your local distributor for more details.

Online ORP Meter from Pi

Although they command a higher price in the market place these sensors are more than cost effective with their longer life and considerably lower maintenance requirements, typically only needing calibration once per two or three months. Online ORP meters and ORP controllers are one of the most common analysers in use today in water treatment and process plants and yet online ORP meters cause continual problems for their operators.

Residual Chlorine Analyser | Free Chlorine Analyser

For pH compensation to be valid it must be done with the highest quality pH sensors and with chlorine sensors that have a reduced susceptibility to varying pH, such as those used in the HaloSense range of residual chlorine analysers. The HaloSense range of Residual Chlorine Analysers are used in many applications requiring the measurement and control of residual chlorine levels.
