FT520 Batch Flow Processor

Swimming pools and spas use chlorine as a disinfectant and so use an analyzer to control the amount of chlorine that gets dosed. The AquaSense Swimming Pool Controller and Spa Controller measures the pool chlorine levels and the pH of the pool and then controls the chlorine and pH levels by controlling the chemical dosing. The AquaSense offers bufferless and reagentless operation and is suitable for commercial, municipal and community swimming pools. The AquaSense has been designed to three criteria:

• Improved Safety – better sensors lead to better process control which leads to less variation in chlorine residuals even with highly variable bathing load.
• Improved Control – better process control leads to reduced chemical usage, lower costs and an improved bathing experience.
• Reduced Costs – lower chemical costs, less expensive controllers, inverter control leading to hugely reduced electrical usage costs are just a few of the ways that the AquaSense can save you money which can pay for a new controller in just a few months.

Key Benefits

Key Benefits

The DioSense chlorine dioxide measurement sensors and flow cells are available with different controllers giving you the same great performance with different communication, display, and chlorine dioxide dosing control options. The two controllers offer different options but both offer the same great user interface and Pi’s great quality.

• Amperometric sensors – continuous online chlorine dioxide ppm measurement
• No chemical reagents – lower cost of ownership
• Stable and reliable – excellent process control
• Suitable for all potable and process waters
• Up to 6 months between maintenance
• No interference from residual chlorine (DioSense M)
• Tolerant of water containing detergents
• Up to 70°C (DioSense NM)
• Up to 6 Bar (DioSense NM)

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

When accuracy and repeatability are critical, such as in pharmaceutical or drinking water applications, the ideal pH electrode will quickly deliver stable measurements. The pH3000 is a research grade pH meter replacement probe specially designed to respond quickly and accurately to rapid temperature changes. The high sensitivity internals also make these electrodes the best choice for low ionic samples. The double junction reference design prevents contamination, allowing pH testing in samples containing heavy metals, proteins and enzymes, or TRIS buffer.

• 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
• Extensive chemical compatibility: Constructed with durable Ultem®, proven in a range of chemical conditions
• Ideal for difficult sample types: Double junction reference protection for testing samples containing heavy metals, TRIS buffer, and other contaminants
• Virtually unbreakable: removable bulb guard protects pH glass and strain relief prevents damage to cable connection
• Ready for wet or corrosive environments: BNC boot protects meter connection
• Compatible with various meters: Versatile replacement probe works with any meter accepting a BNC pH probe

Recommended for: Low ionic samples, medical and pharmaceutical research, biological samples, 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
