Ion selective electrodes

Conventional ion selective electrodes
WTW conventional ion-selective electrode, half cell series 500 Cu 500 DIN
WTW conventional ion-selective electrode, combined - series 800 Cu 500 DIN

Ion selective electrodes for the electro-chemical concentration determination of selected ions - combined electrodes as well as half cells available

  • Cost-effective process with few samples
  • Wide selection of electrodes for different ions
  • Easy handling by combined electrodes

WTW offers a complete range of ion-selective electrodes and meters. You can select from two types:

Half cells Series 500
the half cells of the 500 series for which you will need a reference electrode type R 503 (an exception for this is the gas-sensitive NH 500/2 with integrated reference electrode).

Combined ISE electrodes series 800
The combined electrodes type 800 are excellent in their handling and offer the additional opportunity to also measure small sample volumes, as the ion selective and the reference electrodes are combined in a compact rod. Furthermore, they are convincing with their exceptionally great price/performance ratio.
