TurbSense®

The OzoSense Online Dissolved Ozone Monitor from Pi for the measurement of the ozone concentration in water, is designed to be simple to install and operate, and offers unrivalled stability, accuracy and precision, whilst offering excellent value for money. The OzoSense range of online dissolved ozone analyzers and dissolved ozone monitors utilize the very latest and best ozone sensors available in the world today. There are two sensors in the OzoSense range. The first is a membraned device which is insensitive to changing pH, uses no reagents, is extremely stable, and has reduced maintenance and reduced whole life costs. The second is a non membraned three electrode sensor, that can operate at higher temperatures and pressures.

Product Description

The S272CD online process pH sensor delivers reliable online monitoring for in-line or submersion installation configuration. This sensor is designed to extend sensor lifetime with double-junction technology. Minimal maintenance required due to flat glass measurement surface. A versatile sensor for moderate and multi-purpose applications.

• Reliable performance in demanding applications: Liquid flow naturally cleans the flat pH measurement surface
• Extended sensor lifetime: Double junction technology extends sensor lifetime by preventing reference contamination
• Versatile design for many applications: 3/4″ NPT threads on both ends for submersion or in-line mounting
• One year limited warranty: We stand behind all our products with the Sensorex Guarantee

Product Description

In laboratory environments such as medical, biological, and materials science research groups, samples and test conditions are constantly changing, but accuracy is always critical. The pH3400 is a highly versatile glass combination pH electrode, specially designed to respond quickly and accurately to rapid temperature changes. The high sensitivity internals allow testing of low ionic samples. Safely measure samples containing heavy metals, TRIS buffer, or proteins thanks to the double junction reference design, which prevents fouling. Even test highly reactive chemicals: with a glass body, the pH3400 is inert to a wide range of chemical reactions.

• Our most sensitive laboratory electrode: accurate to 0.04 pH in tests across full recommended temperature range
• Easily maximize measurement repeatability: Rapid renew reference system for quick refilling
• Safe for use with reactive chemicals: Glass bodies are inert to many chemical reactions
• Ideal for difficult sample types: Double junction reference protection for testing samples containing heavy metals, TRIS buffer, and other contaminants
• Ready for wet or corrosive environments: BNC boot protects meter connection

Recommended for: Low ionic samples, medical and pharmaceutical research, biological samples (including TRIS buffer), samples containing heavy metals

Key Benefits

Many water companies want to measure free chlorine residuals without the need for chemical buffers traditionally associated with such measurements. Acetate and phosphate buffers are expensive and environmentally unfriendly. Buffer delivery systems are maintenance intensive and have fairly costly consumables and there are health and safety considerations in the handling of the acids and high disposal costs if the acid treated water is unable to be fed back into the water supply. Amperometric cells and most polarographic probes only respond to hypochlorous acid, (HOCl). HOCl dissociates into hypochlorite (OCl–) in a pH dependent manner. This is why most chlorine monitors need acid buffers in most applications. The typical pH of water measured on a water treatment works may range from 7 to 9.2. Chemical buffering reduces the pH to between 5 and 6 and ensures that the majority of the residual chlorine is present as HOCl (see graph below).

• Low purchase cost
• Low cost of ownership
• Reduced pH dependency (largely pH independent)
• Stable and reliable
• Bufferless
• Reagentless
