Important safety information



Please read these operating instructions carefully and completely
prior to working with the instrument.



Ensure that these operating instructions are always available for
all users.



These operating instructions must always be passed on to the
new owner should Testomat 2000

®

Fe change hands.

Intended use

The process photometer Testomat 2000

®

Fe is a robust wet-chemical

online monitor for monitoring the dissolved iron content (II)+(III) from
0 to 1.0 mg/l using a colourimetric analysis principle.

Analysis is carried out by adding two reagents. The analysis result is
displayed after a reaction time of approx. 7 minutes (absolute meas-
uring time without flushing times).

Applications include, e.g., the monitoring of de-ironing plants or the
monitoring of process or drinking-water flows.

Always adhere to the performance limits stated in the section entitled
“Technical data”.



Always observe the requirements of the medium being measured.

To ensure correct and intended usage, always read and understand
these instructions, especially the sect

ion entitled “Important safety

information”, prior to use.

The instrument is not used as intended if



it is used in areas not specified in these instructions,



it is used in areas which do not correspond to the ones described

in these instructions.

Qualification of the staff

Assembly  and  commissioning  require  fundamental  electrical  and
process engineering knowledge as well as knowledge of the respec-
tive  technical  terms.  Assembly  and  commissioning  should  therefore
only  be  carried  out by  a  specialist  or  by  an  authorised  individual  su-
pervised by a specialist.

A  specialist  is  someone  who due  to  his/her  technical  training,  know-
how and experience as well as knowledge of relevant regulations can
assess  assigned  tasks,  recognise  potential  hazards  and  ensure  ap-
propriate  safety  measures.  A  specialist  should  always  adhere  to  the
relevant technical regulations.



Always adhere to hazard warnings and safety tips when using
reagents, chemicals and cleaning agents. Please adhere to the
respective safety data sheet! Download the safety data sheets for
the supplied reagents at
