ATTENTION
Amperometric systems such as the AMI Trides do not measure
properly if the sample contains even traces of the following
products:
Š
Disinfectants containing stabilisers like cyanuric acid or
5.5-Dimethyldantoin,
Š
Organic chlorine compounds,
Š
Corrosion inhibitors (phosphates),
Š
Detergents used for cleaning purposes,
Š
Traces of brass or copper from sample supply tubes
and connectors.
These substances contaminate sensors, leading to low
readings and hence resulting in chlorine over-dosage.
ATTENTION
Š
Make sure the reference electrode never dries out!
Š
Always ensure that there is sample flow before switching
on the instrument.
