2. Product Description
2.1. Description of the System
This instrument is applicable for the measurement of the specific
conductivity, concentration, salinity and Total Dissolved Solids
(TDS).
Application
range
The conductivity is a parameter for the total quantity of ions present
in the solution.
The AMU Inducon transmitter together with the sensor Indu-
con1000 is used for applications in:
chemical
food & dairy
refinery
pulp & paper
metal finishing
and waste water industries.
Measuring
Principle
Inductive conductivity measurements are carried out as follows:
The transmitter gives a constant drive to one of the toroidal coils
which induces a current in the solution. This induced solution cur-
rent produces a current in the second toroid. The signal measured
by the second toroid is proportional to the solution conductivity.
Inductive conductivity measurements are performed without using
any electrodes in contact with the solution.
Concentration
Measurements
NaCl: max. 17.9–21% 0–50 °C
HCl: max. 10–12% 0–50 °C
NaOH: max. 6.5–9% 0–50 °C
H2SO4: max. 16–22% 0–50 °C
HNO3: max. 17–20.8% 0–50 °C
User defined substance
Salinity (as NaCl) in %
TDS (Total Dissolved Solids) in %
