Zinc Reference Electrode
Zn/ZnSO4 Reference electrodes are permanently installed in soil to facilitate the potential measurement of the protected structures. The electrodes shall be installed close to the protected structure.
The reference electode is used inside internally protected steel water boxes, tanks, pipes etc. and is provided with a 1″ screw-in thread for permanent fixture by using a weld-in flange. The measuring cell is covered with insulating material so that the only exposed area is the circular base at the bottom. Potential referring to H2 electrode: – 0.77 V,
Zinc / Zinc Sulfate reference electrode has the longest life compare to any other reference electrodes. These reference electrodes are available with and without backfill for underground and fresh water applications.
The main components of the permanent solid type zinc reference electrode shall be:
- a cylindrical zinc bar (dia. 20mm, Length 100m) of approx. 63cm2 sensing surface area
- Reference electrode cable connection and cable lead
Linen bag with non polarizing backfill
Bag dimensions:
- ۱۰۰ mm diameter
- ۳۰۰ mm height
The electrodes are designed and manufactured according to purchaser´s requirements for: Operational conditions, temperature and pressure Cable type and length Length of measuring electrode
Portable Zinc reference electrodes are used for tanks & exchangers
