pH2400 Extended Life Glass pH Electrode

Product Description

In harsh laboratory or field conditions, where heat, moisture, or corrosive chemicals may damage equipment, ORP electrode durability is key. The ORP3000 is durable, research grade ORP electrode. All the functional components – the ORP measurement surface, the meter connection, and the cable connection – are reinforced with protective elements. Durable Ultem® body construction provides extensive chemical compatibility and withstands temperatures up to 100°C.

• Virtually unbreakable: removable guard protects ORP measurement surface and strain relief prevents damage to cable connection
• Ideal for difficult sample types: Double junction reference protection for testing samples containing heavy metals, TRIS buffer, and other contaminants
• No maintenance required: Sealed gel reference design does not require users to refill solution
• Extensive chemical compatibility: Constructed with durable Ultem®, proven in a range of chemical conditions
• Ready for wet or corrosive environments: BNC boot protects meter connection

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)

Robust protection and precise integration

The PC-3100 series pH/ORP transmitter has rugged IP 65 enclosure and can be wall, panel, pipe mounted for installation in almost any industrial application. The PC-3100RS offers RS-485 interface to support digital communication to your PLC. The transmitters inherit our reliable technology which features in accurate, robust, and easy to use functions.

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
