+GF+ Signet 2750 pH/ORP Combination Electrode with 80°C Operating Temperature 0-100 PSI Pressure Rating and Double Junction Reference

Product Overview and Core Specifications​

The +GF+ model 727798713 is a Signet 2750 pH/ORP (Oxidation-Reduction Potential) Combination Electrode, a precision sensor designed for critical liquid analysis in demanding industrial processes. This electrode integrates both a measuring element and a reference system into a single, robust unit, simplifying installation and maintenance. Key specifications highlight its advanced design: a double junction reference with Polysulfone junction and KCI gel electrolyte, which significantly reduces contamination and extends service life in harsh chemistries. It features a high-temperature glass membrane suitable for applications up to 80°C and a pressure rating of 0-100 PSI. The sensor is built with a chemical-resistant PVDF body and includes a built-in temperature sensor (NTC 30kΩ) for automatic temperature compensation, ensuring highly accurate readings across its entire operating range.

​Functional Application and Process Role​

The primary function of this sensor is to provide reliable and continuous measurement of pH or ORP levels, which are fundamental parameters for controlling chemical reactions and ensuring process quality. It is engineered for use in a wide array of applications where precise acidity/alkalinity or redox potential monitoring is crucial. This includes pH neutralization in wastewater effluent, cyanide destruction in metal finishing, chlorine control in disinfection systems, and process monitoring in chemical manufacturing and pulp & paper production. The electrode connects directly to a compatible +GF+ Signet transmitter (e.g., 9900 series), which translates its millivolt output into a stable 4-20 mA signal for PLCs, SCADA systems, and other controllers, enabling automated chemical feed control and ensuring processes remain within optimal parameters.

​Distinctive Advantages and Operational Benefits​

The significant advantage of this +GF+ electrode lies in its exceptional durability and low-maintenance design, which directly translates to reduced operating costs and enhanced process uptime. The double junction reference design is a key benefit, as it drastically slows the poisoning of the reference cell by process chemicals, leading to a longer lifespan and more stable readings between calibrations. The pre-gelled, low-maintenance electrolyte eliminates the need for frequent refilling. Its rugged PVDF construction and high-temperature capability ensure reliability in the most challenging environments. For the user, this means fewer sensor replacements, less hands-on maintenance, more consistent process control, and ultimately, improved product quality, regulatory compliance, and cost savings on reagents through tighter control.
