Combination Ion Selective Electrodes

Combination Ion Selective Electrodes

Description

These electrodes can be used with any conventional laboratory or hand held pH meter with a millivolt mode.

Cable length can be specified at the time of ordering. Maximum length is 10 metres. Standard products are fitted with 1 metre of cable terminated with a BNC connector.

Dimensions are: 120x12mm.

Main features and benefits include:

  • No Reference electrode needed
  • Available in fully submersible and water proof format
  • Solid state sensors
  • Ideal for unskilled operatives
  • No filling solution required
  • Virtually unbreakable
  • Can be left dry for long periods
  • Long lifetime
