IP800 Fixed Depth Insertion Paddlewheel

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

Key Benefits

The ORPSense range of ORP Meters from Pi utilize the very latest and best ORP sensors available in the world today for measuring the online Redox potential of any aqueous solution. They are platinum ball based sensors with integral reference electrodes which use no reagents, are extremely stable, and have reduced maintenance and reduced whole life costs. Online ORP meters and ORP controllers are one of the most common analyzers in use today in water treatment and process plants and yet online ORP meters cause continual problems for their operators. What is needed is a stable, reliable, online ORP meter for a reasonable cost. That is exactly what you get with the ORPSense and the ORPSense Automatic Calibrator. The ORPSense sensors and flow cells are available with different controllers giving you the same great performance with different communication, display, and control options. With the ORPSense range of ORP meters, you get everything that you need – and nothing that you don’t.

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

• Inverter control for massive electricity and CO2 savings

• Low purchase cost
• Low cost of ownership
• SMS text alarms
• Remote access via Internet
• Suitable for fresh water, salt water and outdoor pools with cyanuric acid
• Private label option for re-sellers
• Other inputs to data log and alarms
