​•  In-line or submersible mounting
  


 
 

The Signet 2839-2842 series of conductivity electrodes is available in four cell constants from 0.01 to 10.0 cm-1 and are designed for a variety of applications from high purity water quality monitoring to demineraliser regeneration. 316SS electrode surface finishes are controlled in a precision bead blasting operation to ensure measurement accuracy and repeatability. The PEEK insulator and process connections are injection over-moulded to minimise variance between electrodes. Double threaded connections enable quick and easy installation in submersible or in-line configurations. Transmitter integral mounting kit and J-Boxes are available as accessories.

Features of the Signet series of Conductivity Electrodes include:

• Controlled surface finish ensures accuracy and repeatability
• 316SS electrodes with injection moulded PEEK process connections and insulators
• Compact electrode length for easy in-line installation
• Suitable for operation up to 131°C (268°F)
• 3/4 in. NPT or ISO 7/1 – R 3/4 process connections
• Double-threaded connection for in-line or submersible mount
• Triple orifice flow-through design reduces clogging and bubble entrapment
• Cell constants may be traceable to NIST and certified to within ±1% of value
• Integral Mounting Kit and J-Box accessories

Typical 2839-2842 Conductivity Electrodes Applications:

• Water treatment & water quality monitoring
• Reverse osmosis
• Deionization
• Cooling tower
• Boiler protection
• Distillation/desalination
• Demineralizer
• Semiconductor
• Aquatic animal life support systems
