Operating Instructions
The Signet 2724-2726 and 2734-2736 Series of pH and ORP electrodes are designed
to minimize maintenance time and maximize value.
•
The unique DryLoc ® connector provides quick assembly and a secure
connection featuring gold-plated contacts and an O-ring seal.
• The patented design features a lengthened reference chamber pathway to
extend the operational life of the electrode.
• Wetted materials are selected to withstand a wide array of industrial applications.
• Multiple mounting features address the need for installation fl exibility.
These electrodes can be threaded into ¾ in. NPT or ISO 7/1 R¾ inch pipe fi ttings,
submerged in a tank, or mounted into familiar Signet installation fi ttings.
• To build a stand-alone, self-contained pH control system, combine the
2724-2726 electrodes with a 2760 pH Preamplifi er and add a 8750 pH/ORP
Transmitter to move your control capability to the next level.
• Combine the 2427-2726 or 2734-2736 electrodes with the
2750 pH Sensor Electronics to provide a 4 to 20 mA loop to a
Programmable Logic Controller (PLC), SCADA system, or datalogger.
• For more fl exibility and unique features, pair the 2724-2726 or 2734-2736 series
with a 2750 pH/ORP Sensor Electronics and the new 9900 Transmitter.
• Connect up to six 2724-2726 or 2734-2736 electrodes to one 8900 Multi-Parameter
Controller with six 2750 pH/ORP Sensor Electronics using digital (S
3 L) serial data
output for a truly amazing set of features, options, and measurements.
• The 2724-2726 electrodes are recommended for general purpose applications.
• The 2734-2736 electrodes are recommended for harsh applications.
• The 2734-2736 electrodes utilize advanced reference technology to extend
electrode life in all applications.
