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

®

Polymer change hands.

Intended use

The process photometer Testomat 2000

®

Polymer is a robust wet-

chemical online monitor for monitoring the polyacrylate content from
0 to 50 mg/l (ppm) (with the factor set to 1.00) using the photometric
analysis principle. The feed water must be clear, colourless and free
of undissolved particles. Applications include, e.g., the monitoring of
conditioning agents in cooling and heating circuits.



Always adhere to the performance limits stated in the section

entitled “Technical data”.



Always observe the application areas/application limits of the

reagents and the requirements of the medium being measured.

To ensure correct and intended usage, always read and understand
these instructions, especially the section 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
respective  technical  terms.  Assembly  and  commissioning  should
therefore  only  be  carried  out  by  a  specialist  or  by  an  authorised
individual supervised 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
appropriate  safety  measures.  A  specialist  should  always  adhere  to
the relevant technical regulations.



Always adhere to hazard warnings and safety information 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
