The GF Signet 2734-2736 pH / ORP electrodes have a large area PTFE reference junction, salt bridge and reference electrode that are constructed to increase the total reference effectiveness, resist chemical attack, and ensure long service life.
The DryLoc connector with corrosion resistant gold plated contacts readily connects the sensor to the mating 2750 sensor electronics. The robust Ryton threaded sensor body and choice of flat, bulb pH, or flat ORP sensing elements provide a broad range of chemical compatibility for a wide variety of applications. There is an optional pH sensing version available for applications with HF. The HF version is for applications where traces of hydrofluoric acid (2% or less) will attack standard pH glass in levels of pH 6 and below.
The PT1000 temperature sensor offers quick temperature response and allows compatibility with the Signet 8900 and 9900 instruments.
These electrodes are ideal for a wide range of harsh applications. The sensors incorporate 3/4 inch NPT or ISO 7/1-R 3/4 threads for installing into standard pipe-tees. They can also be mounted directly into Signet standard fittings, DN15 to DN100 (1/2 to 4 inch).
Applications for GF Signet 2734-2736 pH / ORP Electrodes
Water & wastewater treatment
Neutralization systems
Effluent monitoring
Sanitization systems
Pool & spa control
Aquatic animal life support systems
Process control
Cooling towers
Please note some advice on best use of these electrodes:
Use the flat glass electrodes when a self-cleaning feature is desired; especially useful in applications with abrasive chemicals.
Use bulb protected electrodes for general purpose applications.
ORP electrodes are generally used for chemical reaction monitoring, not control.
Ensure that sensor materials are chemically compatible with the process liquid.
Keep electrode tip wet, avoid air pockets and sediment.
