Work area
Always keep the area clean to avoid and/or discover emissions.
Recycling guidelines
EWC code: 16 02 16
Always recycle according to these guidelines:
1. If the unit or parts are accepted by an authorized recycling company, then follow local recycling
laws and regulations.
2. If the unit or parts are not accepted by an authorized recycling company, then return them to
the nearest representative.
Waste and emissions regulations
Observe these safety regulations regarding waste and emissions:

Transportation and
storage
Storage
An unsuitable transportation or storage can cause damages.
Use original box to pack the amperometric cell.
Observe storage conditions also for transportation.
Although packed, always protect the unit against humidity and the action of
chemicals.
Before returning the probe to the manufacturer repair service, refer to ⎘
Decommissioning.
DO NOT DISCARD PACKAGING. USE IT TO RETURN THE PROBE.
To store the probe refer to ⎘Decommissioning.
1. Clean the electrode, refer to ⎘ Cleaning procedure.
2. Store the probe in the original box, protected against sun, chemicals and humidity.
Transportation and storage temperature ..... +10°C - +50°C (+32°F - +122°F)
Humidity .................................................... 95% relative humidity (not condensed)

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.
