1. FEATURES

* One meter for multi purpose operation :

Conductivity, TDS ( Total dissolved solids ), Salt measurement.

*Conductivity : 200 uS/2 mS/20 mS/200 mS.

* Salt : 0 to 12 % salt ( % weight ).

* Conductivity measurement can select Temp. Coefficient

of measurement solution.

*ATC for the conductivity measurement.
