General presentation
The TPM870 Turbidity Pump Module is used to interface a turbidimeter
fitted with an analogue measurement output (example the 2100AN IS
turbidimeter from Hach) and a Titration Workstation of the TIM8xx/
TIM9xx range or a ION450/ION570 Ion Analyser.
The TPM870 allows to automate turbidity measurements in association
with pH and conductivity measurements and a potentiometric titration
like water hardness determination for example.
With a PC connected to the Titration Workstation and the TitraMaster 85
PC software, the analysis can be fully automatised and the
measurements collected on the PC.
Présentation générale
Le Module Pompe Turbidité TPM870 est utilisé pour interfacer un
turbidimètre équipé d'une sortie de mesure analogique (exemple : le
turbidimètre 2100AN IS de chez Hach) avec une Station de Titrage de la
gamme TIM8xx/TIM9xx ou un Analyseur d'Ions ION450/ION570.
Le TPM870 permet d'automatiser la mesure de la turbidité en associa-
tion avec la mesure de pH, de conductivité et un titrage potentiométrique
comme la détermination de la dureté de l'eau par exemple.
Avec un PC connecté à la Station de Titrage et le logiciel PC
TitraMaster 85, l'analyse peut être entièrement automatisée et les
mesures récupérées dans le PC.

1. Setting up
The TPM870 instrument has been developed to meet the requirements of
electrochemical applications dedicated to water analysis. It is therefore
aimed at experienced users who have the knowledge required to operate
the instrument and implement the security instructions enclosed. We
accept no responsibility for using this measurement system (including
peripheral devices) under conditions that are not specified in this User's
Manual. This system must not, under any circumstances, be used to
perform tests on living beings.
1.1 Equipment used
.A TPM870 Turbidity Pump Module to add turbidity measure
automation to TitraLab or MeterLab system configurations (see table
below), R21T112 (in 230 V) or R21T113 (in 115V).
.A turbidimeter with an analogue measurement output (example:
2100AN IS turbidimeter from Hach).
.A manual Flow Cell Kit for 2100AN IS turbidimeter from Hach.
.< 0.1, 20, 200, 1000, 4000 and 7500 NTU standards.
.A Titration Workstation of the TIM8xx/TIM9xx range or an Ion
Analyser IONxxx. The TIM8xx, TIM9xx or IONxxx used depends on
the applications to be done.

1.2 Hydraulics circuit
1.2.1 Operation principle
The sample is driven into the turbidity flow cell (3) with pump (2) after
electrovalve (1) has opened. The sample is evacuated to a waste.
Rinsing water is driven into the turbidity flow cell (3) with pump (2) after
electrovalve (4) has opened. Rinsing water is evacuated to a waste as
for the sample.
Electrovalves (1) and (6) and pump (2) are monitored via the TTL
commands of the instrument used for the electrochemical
measurements. Manual rinse can be triggered by pushing button (5).

1.2.2 Setting up the hydraulics circuit
We recommend you to place the Hach 2100AN IS turbidimeter onto the
TPM870 and the Titration workstation or Ion Analyser on the left or right
side of these two instruments. The waste and rinse water containers can
be placed on the floor. Have in mind that around 150 ml of rinse water
are required per sample analysis. According to the number of samples to
analyse, it could be interesting to take the rinse water directly from an
ion exchanging column output.
Recommended position and space required
The Sample Changer can be placed on the right or on the left of the
system defined above. Place the extension burette (ABU52 or ABU62)
beside the Titration workstation or Ion Analyser.
