• Product Description

    pH measurement is usually done with the use of a combination electrode. The combination electrode is an electrode system formed by a glass sensing half-cell and an internal reference half-cell. As the reference junction acts as the medium of conductor between the reference electrolyte and the sample to be measured, it must allow free movement of electrons through the junction and into the sample The selection of a suitable electrode depends on the types of application Eutech’s pH /ORP combination electrodes offer the convenience of having the reference and measuring electrodes combined in a single housing. They are offered in a variety of configurations to suit most laboratory and field application needs. Choose from two models: single-or double-junction, sealed (gel-filled) or refillable
    Single Junction
    Ideal for general-purpose applications. Ag+ ions are in contact with junction and this can cause chemical interaction with sulphur. Not suitable for biological samples or tris buffers
    Double Junction
    Prevents interference between the inner fill solution and sample. Electrolyte is free of Ag+ ions. Suitable for use with biological samples. Can be used in place of calomel reference electrodes
    Sealed(gel-filled)
    No refill hole. The reference electrolyte is usually a gel. Replacement of the electrode is necessary when it gets contaminated. Virtually no maintenance is required
    Refillable
    Refill hole allows reference electrolyte replenishment. Can be used many times over. Needs refilling when fill solution is low Choose single junction ORP electrodes for field, clean water, and other general-purpose applications or double junction electrodes for samples containing heavy metals and organics. Platinum sensors are suitable for most general uses pH Electrodes (General Glass) & (General Plastic)

Platinum sensors are suitable for most general uses pH Electrodes (General Glass) & (General Plastic)  
  • Product Description

    pH measurement is usually done with the use of a combination electrode. The combination electrode is an electrode system formed by a glass sensing half-cell and an internal reference half-cell. As the reference junction acts as the medium of conductor between the reference electrolyte and the sample to be measured, it must allow free movement of electrons through the junction and into the sample The selection of a suitable electrode depends on the types of application Eutech’s pH /ORP combination electrodes offer the convenience of having the reference and measuring electrodes combined in a single housing. They are offered in a variety of configurations to suit most laboratory and field application needs. Choose from two models: single-or double-junction, sealed (gel-filled) or refillable
    Single Junction
    Ideal for general-purpose applications. Ag+ ions are in contact with junction and this can cause chemical interaction with sulphur. Not suitable for biological samples or tris buffers
    Double Junction
    Prevents interference between the inner fill solution and sample. Electrolyte is free of Ag+ ions. Suitable for use with biological samples. Can be used in place of calomel reference electrodes
    Sealed(gel-filled)
    No refill hole. The reference electrolyte is usually a gel. Replacement of the electrode is necessary when it gets contaminated. Virtually no maintenance is required
    Refillable
    Refill hole allows reference electrolyte replenishment. Can be used many times over. Needs refilling when fill solution is low Choose single junction ORP electrodes for field, clean water, and other general-purpose applications or double junction electrodes for samples containing heavy metals and organics.
