Endress+Hauser CPK9-H127A | pH/ORP Reference Electrode Cable, TOP68 Plug
Endress+Hauser CPK9-H127A high-impedance coaxial cable. For pH/ORP reference electrodes with TOP68 plug, 7.2mm Ø PVC sheath, IP68 plug head, -25°C to +80°C.
Product Overview
The Endress+Hauser CPK9-H127A is a specialized coaxial reference cable used to connect pH or redox (ORP) reference electrodes (with TOP68 connector) to a transmitter or measuring instrument. It features a TOP68 plug head with IP68 protection and a PVC outer sheath. This cable is part of the CPK9 series and is typically used in laboratory, field, or process applications where a separate reference electrode needs to be connected alongside the measuring electrode.

Key Features
-
TOP68 Connector: Secure, IP68-rated threaded connection for reference electrodes; plug head is rotatable for easy orientation.
-
Signal Integrity: Coaxial construction with high insulation resistance for accurate transmission of the low-current reference potential.
-
Robust Design: PVC sheath resists water, oils, and mild chemicals in standard industrial and laboratory environments.
-
Matched Pair Usage: Typically paired with a CPK1/CPK2 cable for the measuring electrode to complete the 2-electrode pH/ORP measurement loop.
Applications
-
Laboratory & Field Analysis: Connecting separate reference electrodes to portable or benchtop pH meters.
-
Process Analytics: As part of a 2-electrode (measuring + reference) sensor installation with separate transmitter connection.
-
Water Quality Testing: Where a combined pH/reference sensor is not used and a dedicated reference half-cell is required.
