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 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
