1 PRODUCT PRESENTATION
1.1 FUNCTIONAL PURPOSE OF THE EC1200
The basic system for EC and temperature measuring is made of three parts:
-
the meter described in this instruction manual;
-
a conductivity cell with 2 electrodes
-
a Pt1000 temperature sensor
The instrument has the necessary electric circuits and firmware to perform the following functions:
1) as the proper sensor is connected, it displays the EC and temperature values;
2) if a Pt1000 temperature sensor is connected, it will display the temperature values;
3) it performs an automatic or manual temperature compensation for EC measures;
4) it performs the manual or automatic EC calibration
5) it allows the memorization and the visualization up to 80 readings
1.2 FUNCTIONAL PRINCIPLES
The conductivity meter is used to detect the electric conductivity of liquids and to control the salt
content or the ionic concentrations of liquids.
In order to prevent the electrodes polarisation, the measuring is done by alternate current.
The temperature changing of the sample may cause a considerable error, because of the changing of
the ions activity.
This instrument features a manual or automatic temperature compensation, referred to temperature
of 20 °C or 25 °C.
