ECL Series is designed for measuring free chlorine (both organic and inorganic).
Open amperometric cells comprise an Off-line probe holders, a sensing electrode and a flow electrode.
Probe holders can contain up to three probes (temperature, pH and ORP).
The flow of water within this cell must remain constant and within 40 l/h. A pressure stabilizer is
available for areas subject to sudden pressure changes.
It is recommended to instal a filter before the probe holder.
Suitable for non-clean water thanks to the presence of cleaning balls.

ECL amperometric cells have an amperometric measuring system.
Measurement method is an electrochemical technique: the two electrodes (platinum and copper, or
platinum and silver) produces a current directly proportional to the concentration of chlorine.
Before any operation (preparation, cleaning and replacements) and before handly the
amperometric cell you MUST FOLLOW these PRECAUTIONS.

Precautions
WEAR UNPOWDERED NITRILE GLOVES.
Avoid contact of the electrolyte with the skin.
In case of contact with skin, rinse immediately with plenty of water.
WEAR EYE PROTECTION
Avoid contact of the electrolyte with the eyes.
In case of contact with eyes, rinse immediately with plenty of water
and seek medical advice.
