pH Guide


HORIBA's superior electrode technology has produced unparalleled tough pH glass bulbs and unique flat sensors. Electrodes have different designs to cater a wide range of applications - from pure water to complex samples. Select the suitable electrode that is specially designed for your application.

  • Plastic-body pH electrodes, either refillable or gel-filled, are ideal for field measurement. 
  • The glass membrane of refillable electrode offers excellent response to low conductivity water. When the refilling port is covered with the movable slider, the electrode can be used in submerged measurements for up to 30 minutes in 1m depth of water. 
  • Gel-filled pH electrode does not require refilling.
  • ToupH electrodes are more impact-resistant than conventional glass-body pH electrodes due to their thick glass membrane. These electrodes are recommended for general laboratory samples.

This plastic-body, gel-filled pH electrode with integrated temperature sensor is ideal for field testing. The body is durable and no need to refill the electrode.

This plastic-body, refillable pH electrode with integrated temperature sensor is recommended for general-purpose use. 

This glass-body, refillable pH electrode with integrated temperature sensor is recommended for a wide range of applications, including pH buffers and aqueous test solutions.
