詳細英文介紹

2724-2726 pH-ORP Electrodes

The Signet 2724-2726 pH and ORP Electrodes features a patented reference electrode design and uses the unique foul-proof patented DryLoc® connector. The large area PE reference junction and pathway is constructed to increase the total reference effectiveness and ensures long service life.

The DryLoc connector with corrosion resistant gold plated contacts readily connects the sensor to the mating 2760 preamplifier or the 2750 sensor electronics. The robust Ryton® threaded sensor body and choice of flat pH, bulb pH, or flat ORP sensing elements provides broad range of chemical compatibility for a wide variety of applications.

There are two optional sensing versions, HF and LC, available. The quick temperature response is available in either a PT1000 or 3 KΩ temperature sensor and allows compatibility with all Signet pH/ORP instruments. The 2724-2726 electrodes are general-purpose sensors ideal for a wide range of applications. The sensors incorporate ¾” NPT or ISO 7-1 R¾ threads for installing into standard pipe-tees. They can also be mounted directly into Signet standard fittings.

Fields of Application:

• Water & Wastewater Treatment
• Neutralisation Systems
• Scrubber Control
• Effluent Monitoring
• Surface Finishing
• Heavy Metal Removal and Recovery
• Toxics Destruction
• Sanitization Systems
• Commercial Pools & Spas
• Aquatic Animal Life Support Systems
• Process Control

Advantages:

• Designed for use with 2750 Sensor
• Foul-proof connector
• Gold-plated contacts
• Self-cleaning flat versions reduce risk of glass breakage
• Large reference volume and solid polymer electrolyte
• HF option for pH
