pH Sensors

The 2724-2726 pH and ORP electrodes are general purpose sensors ideal for a wide range of applications. These feature a patented reference design and use 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 2751 pH/ORP Smart Sensor Electronics. The robust PPS threaded sensor body and choice of flat pH, bulb pH, or flat ORP sensing elements allows a broad range of chemical and mechanical compatibility for a wide variety of applications.

The GF 2734-2736 pH and ORP electrodes are ideal for a wide range of harsh applications with low concentrations of poisoning ions, and chemicals that react with silver ion, Ag+. The superior glass formulation provides excellent chemicals resistance in acidic and alkaline/ caustic environments. The large area PTFE reference junction, salt bridge and reference electrode are constructed to increase the total reference effectiveness, resist chemical attack, help resist coating, and ensure long service life in harsh applications.

The Type 2756-2757 Wet-Tap pH and ORP electrodes are general purpose sensors ideal for a wide range of applications where the installation and removal of the electrode can be performed without the need for system shutdown.

The Type 3719 pH/ORP Wet-Tap Assembly allows installation and removal of pH or ORP electrodes, even under process pressure, without the needs for process shutdown during routine electrode maintenance and calibration. Process isolation is achieved during electrode retraction with two sets of double O-ring seals on a unique and compact retraction assembly; no separate valve is required.

The GF 2760 pH/ORP Preamplifiers feature a DryLoc® connector, providing a robust connection to GF DryLoc electrodes. The 2760 preamplifier allows DryLoc pH/ORP electrodes to work with GF ProcessPro® and ProPoint® pH/ORP instruments. The DryLoc electrode connector system quickly forms a robust assembly for submersible and in-line installations. Optional NEMA 4X junction enclosures extend the preamplifier cable to long distances.

The Type 2774-2777 pH and ORP electrodes are high performance sensors ideal for a wide range of applications. The unique foul-proof DryLoc® connector with gold-plated contacts is designed specifically for use with the type 2751 pH/ORP Smart Sensor Electronics. These dependable and highly responsive electrodes feature a PTFE double reference junction with potassium nitrate (KNO3) in the front chamber to block various poisoning ions such as Copper (CU2+), Lead (Pb2+), Mercury (Hg2+), and a large reference chamber that combine to extend the service-life.

The Type 3719 pH/ORP Wet-Tap allows installation and removal of pH or ORP electrodes under process pressure, without the need for process shutdown during routine electrode maintenance and calibration.

Process isolation is achieved during electrode retraction with two sets of double O-ring seals on a unique and compact retraction assembly. No separate valve is therefore required. The Wet-Tap body design allows for full access to the plunger and internal O-rings, to easily perform maintenance such as lubrication/ replacement of O-rings and the cleaning of the internal plunger/ housing.

A patented cam-activated automatic locking mechanism, SafeLoc™, and the short stroke design help to assure operator safety. The Wet-Tap unit can be mounted at any angle and can be used with the GF DryLoc® Wet-Tap electrodes.
