Preface 

This manual serves to explain the use of the Conductivity and TDS handheld 
meters. The models covered are the CON 6 and TDS 6. 

This manual functions in two ways: first as a step by step guide to help you 
operate the meter; second, it serves as a handy reference guide. 

This manual is written to cover as many anticipated applications of the 
Conductivity and TDS handheld meters as possible. If there are doubts in the 
use of the Conductivity and TDS handheld meters, please do not hesitate to 
contact the nearest Eutech Instruments/ Oakton Instruments Authorized 
Distributor. 

Eutech Instruments/ Oakton Instruments will not accept any responsibility for 
damage or malfunction to the meter caused by improper use of the instrument.  

The information presented in this manual is subjected to change without notice 
as improvements are made, and does not represent a commitment on the part 
of Eutech Instruments Pte Ltd/ Oakton Instruments.
