Metallic electrode 53 55
Introduction
The 53 55 is a platinum low maintenance
electrode for wastewater.
SAFETY NOTE
Before use with hazardous substances, find out about the relevant hazards, protective measures, and what
to do in an emergency.
Electrode preparation
• Remove the storage protector
Installation
In immersion, insertion, flotation housings, etc. with PG 13,5 thread.
See Housing instruction manual.
In some cases the electrode is installed,
with the help of sockets and adapters,
directly onto pipes.
Cable. They are connected to coaxial
cables with an AS9 connector.
Calibration
See pH-meter instruction manual.
Measurements. Recommendations
• During measurement the samples must
be slightly stirred.
• The sample must cover the electrode’s
diaphragm
• After measurement, rinse the electrode
with distilled water. Dry it with soft tissue.
• Between measurements the electrode
should be immersed in aqueous solution. The most appropriate place is the
storage protector with some electrolyte.
Maintenance
• Diaphragm cleaning: use the diaphragm
cleaning solution, code LZW9600.
• Platinum ring cleaning: can be ribbed with
soft abrasive, for example tooth paste.
Troubleshooting
... the pH-meter always measures the
same value.
Short circuit in the electrode, cable or
connector.
Substitute the electrode.
... fortuitous reading.
Broken cable.
Substitute the electrode.
... very slow response.
Dirt on the diaphragm and/or the metalic ring.
Reference system worn out.
Clean, regenerate or replace the
electrode.
Storage
The connector should be protected from
humidity by the protective cap
Place the electrode in the storage protector
with KCl + glycerine.
Life of an electrode
The life expectancy of the electrode could
be indefinite when the suitable maintenance is applied.
