Replacement Electrode for the Horiba LAQUA Twin Salt Meter B-721

Features: B-721-Sensor-s

  • Flat electrode design requires very small sample size (0.3mL) 
  • Selective ion electrode ignores pH and other ions
  • Easy to replace design simply snaps into place 
  • Built-in cover protects the electrode from damage 

This replacement electrode is designed to snap into a B-721 Horiba LAQUA Salt Testing Meter. As older electrodes are damaged or stop operating correctly they should be replaced to ensure accurate testing. The old electrode is easy to remove from the meter and this new electrode snaps into the same space. This sensor is designed to ignore the pH and other ions to ensure accurate testing of salt concentrations.

It requires a very small sample size of only 0.3mL and helps to save on samples as well as calibration solutions. Using this replacement electrode saves the user money from having to purchase an entire new meter and allows for indefinite testing with the B-721 meter.
