Conductivity measurement procedure 

6.4.2

6.4.2.1

 

General points 

 

The global quantity of dissolved solids in water can be measured by the CONDUCTIVITY (expressed in 
microsiemens per centimeter (µS / cm). 

6.4.2.2

 

Conductivity «water purifier outlet» 

6.4.2.2.1

 

Checking the output conductivity for VERSION 1 

 

1.

 

Let flowing the water to test 15 to 30 seconds. 

2.

 

Remove the conductivity meter protection cap. 

3.

 

Rince the protection cap and the conductivity meter probe with the water to test. 

4.

 

Renew the operation 2 to 3 times. 

5.

 

Fill protection cap of the conductivity meter with the water to test then plunge the 
conductivity meter: read the measured value. 

6.

 

Renew the operation 2 to 3 times; the retained value will be the last measurement one. 

7.

 

Switch off the conductivity meter then put back the protection cap. 

 

 

 

INTERPRETATION OF THE VALUE OF THE CONDUCTIVITY OF PURIFIED WATER 

Conductivity <1 μS/cm

 

Class 2 water (according to ISO 3696) 
 
Water of very good quality; no impact on the quality of the 
analyzes 

1 μS/cm <Conductivity <5 μS/cm 

Class 3 water (according to ISO 3696) 
If the desired water class is class 2, then change the resin 
bottle. See paragraph 6.4.9 
In any case, the resin bottle will have to be changed soon 

Conductivity> 5 μS/cm

 

Change the resin bottle immediately. See paragraph 6.4.9
