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

Product Description

When measuring samples such as wastewaster that may contain proteins, heavy metals, or other contaminants, it is important to use an ORP sensor (REDOX sensor) designed to withstand unpredictable chemical environments. The ORP2000 features double junction reference protection, which prevents contamination by sample components that interact with silver (Ag). The durable Ultem® body ensures extensive chemical compatibility, making the ORP2000 a highly versatile analytical tool.

• Virtually unbreakable with durable Ultem® body construction and recessed protected glass
• Reliable and accurate ORP / REDOX measurements
• No refilling or maintenance required with sealed gel-filled design
• Instantly ready for use and shipped in storage bottle for long shelf life – guaranteed for one year
• One year limited warranty

Product Description

Whether you are a student measuring pH in a lab or a business owner monitoring plant or crop health, you need a pH probe that will consistently deliver accurate measurements. If you deal with a wide variety of chemicals or any aggressive substances, a glass pH probe like our pH1400 is a safe choice due to the chemically inert properties of glass. This basic, single junction electrode has a refillable reference cell, allowing users to maintain measurement precision throughout instrument lifetime.

• Accurate measurements across full pH scale (0-14)
• Easily maximize measurement repeatability: refillable reference cell with liquid solution
• Maximum chemical compatibility: glass probe body is inert to most reactions
• Compatible with a variety of pH meters: use this probe with any pH meter accepting BNC
• Instantly ready for use: Shipped in storage bottle for long shelf life – guaranteed for one year
• One year limited warranty: We stand behind all our products with the Sensorex Guarantee

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.
