Ion Selective Sensors and Electrodes

Google Search Our Web Site:

All of our Ion Selective (ISE) electrodes are available in many shapes and lengths to fit a wide variety of applications.

These Ion Selective Electrodes are designed to work with any modern pH/mV meter, ISE/concentration meter, or suitable on-line instrumentation.

Our Ion Selective Electrodes have several advantages over colorimetric, gravimetric, and other methods:

  • They can be used from 0.1 to 10,000 ppm.
  • The ISE electrode bodies are shock-proof and chemically-resistant.
  • The Ion Selective Electrodes, once calibrated, can monitor concentration continuously and analyze the sample within 1 to 2 minutes.
  • The Ion Selective Electrodes can be placed directly into the sample without sample pretreatment or destruction of the sample.

Best of all, Ion Selective Electrodes are inexpensive and great screening tools for identifying dissolved salts in samples.
