+GF+ Signet 2724-2726 pH/ORP Electrodes
+GF+ Signet 2724-2726 pH/ORP Electrodes
Describe
Compatible with ALL Signet pH/ORP Instruments

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 pH sensing versions available,
HF and LC. 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 LC
version can be used for low conductivity fluids 20 - 100
μS/cm nominal and below 20 μS when mounted under
controlled conditions.
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 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 (½ to 4 inch)
