pH Sensors

Laboratory pH Sensors and Ion Selective (ISE) Sensors.

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 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.
  • Once calibrated, can monitor concentration continuously and analyze the sample within 1 to 2 minutes.
  • Can be placed directly into the sample without sample pre-treatment or destruction of the sample.
  • Inexpensive and great screening tools for identifying dissolved salts in samples.

Currently we manufacture sensors for numerous specific ion measurements. These can be supplied with various options including Mono or Combination, Sealed or Refillable, Rebuildable Sensing Tips, Flushable Reference Junctions and Specialized Reference Electrodes to minimize interference. Direct Replacements are available for all major brands.

VLC currently offers the following Ion Selective Electrodes (ISE):

Call 1-877 291 5572 with your OEM Part Numbers for Quick Cross-Referencing.

Conductivity Sensor

Toroidal Conductivity Loop Powered Transmitter Sensor

This Conductivity monitoring system consists of a loop powered transmitter and an electrodeless conductivity sensor in a single package. Temperature compensation is accomplished with a RTD Pt100 built-in to sensor.

Application includes water treatment, cooling tower and water monitoring.

Principle of Operation:

When the electrodeless Conductivity sensor is immersed in the solution to be measured a conductive loop is created through the two toroidally wound coils. An alternating current is applied to one of the coils, which includes a current in the conductive loop. The second coil is used to measure the Conductivity, which is proportional to the induced current in the solution.

The advantages of the electrodeless method are more apparent in measurement applications in which electrode contamination and polarization of a conventional Conductivity system can lead to erroneous readings
