Copper Combination ISE


Copper Combination ISE with 1 Metre Cable.

SKU: 3227 Category: Tags: ,

Here are some of the benefits of using the EDT directION Copper Combination ISE:

  • Rugged Solid State Sensor
  • No Filling solutions
  • No membrane replacements
  • Built in dry Reference electrode
  • Waterproof and submersible
  • Suitable for Laboratory and Field work
  • Compatible with all pH and Ion Meters
  • Stored dry for long lifetime
  • Low cost
  • Easy to use

The Cupric Sensor is a crystalline material which can be polished when the slope decreases over its lifetime. This will rejuvenate the sensor and give a longer lifetime. Store the sensor dry with the protective cap on.

Each EDT directION Combination ISE has a 1 metre cable and a BNC connector. This allows for use with all types of pH/ION meter including laboratory bench and research models. Other connectors are available on request.

For direct concentration reading and absolute simplicity the EDT QP459 pH/ION meter is the perfect instrument for these ISEs. The solid state sensors have a huge advantage over conventional ISEs because there is no internal fill solution to degenerate the sensor. This means that EDT directION combination ISEs have an unrivalled lifetime and a very low cost of ownership.
