Introduction
This operating instruction describes installation, operation and programming of the analysis unit Testomat
®
ECO.
We recommend that, whilst familiarising yourself with the operation of the unit aided by this manual, you have
immediate access to the unit in order to perform the functions and combinations as described. As certain functions are
interrelated, it is advisable to follow the instructions in the given order.
Should problems or questions arise which are not described in this manual and/or cannot be solved, our customer
service is always at your disposal.
Try to identify the problem as accurately as possible and record the conditions under which it has occurred. This will
enable us to offer you swift effective assistance.

Short description
The Testomat
®
ECO is used for the automatic measuring and monitoring of the total water hardness.
The parameter to be measured is determined by the choice of the reagent and by the corresponding user program.
Reagents available for the Testomat
®
ECO
The various measuring parameters and ranges are determined by the choice of the reagents. The table gives a
summary of the different possibilities.

A consistently reliable result can be guaranteed by the TESTOMAT
®
ECO only with the use of original
HEYL Testomat
®
2000 reagents !
Failure or problems which are caused by the use of different indicators
are not covered by the warranty or refund services.
When monitoring residual/total hardness, larger quantities of heavy-metal ions in the softened water can affect
the colour reaction, especially iron above 0.5 mg/l, copper above 0.1 mg/l and aluminium above 0.1 mg/l
(brownish-red colour indication).The measuring is possible in a range of pH 4-10.5.
At a concentration of more than 100 mg/l of CO
2
(carbon dioxide) in the water, the excess carbon dioxide must
be removed by installing a Type R aerator in the feed water line to the TESTOMAT
®
ECO unit. When using the
TESTOMAT
®
ECO for monitoring a de-carbonisation installation (weakly acidic cation exchanger) without its
own irrigator, a small scale irrigator must always be installed upstream of the
device.
Concentration values of these ingredients can be determined safely and simply with our TESTOVAL colorimetric test
comparators.
