ESZ Mendeleevets - Zinc reference electrode

Certification:

Application area

Zinc reference electrode ESZ Mendeleevets is used in the electrochemical protection systems for measuring construction potential relative to the environment. The electrodes have 2 modifications – ESZ-1 and ESZ-2.

Electrodes ESZ-1 and ESZ-2 are installed direct in water, including sea water.

Electrodes ESZ-2 are also intended for installation in water electrolyte solutions – commercial water from watery oil, naphtha, diesel fuel, gas condensate, black oil, vacuum gas-oil.

Technical details

ESZ-1 represents itself a zinc electrode electrically connected to a measuring cable, installed in a plastic casing and sealed with a compound.

ESZ-2 represents itself a zinc electrode installed in a fluoropolymer casing and sealed by cable entries.

For connection to a terminal block, the measuring cable of electrodes is equipped with a cable termination. The joint of the measuring cable and the cable termination is insulated by a heat shrink tube.
