pH & mV

* Two special pH measurement modes for high purified water and purified water withammonia can be set to meet the requirement of the electric powerand petrochemical industry.

* "EH" oxidation-reduction potential (ORP) measurement mode can be set.

Conductivity 

* Advanced conductivity measurement technique,employing two-cell conductivity electrode (K = 1), only need one-point calibration, able to reach the measurement precisionrange of 0.5μS/cm~ 200mS/cm. 

*Forhigh purity waterof less than 10μS/cm, no need to switch measurement mode,automatic non-linear temperature compensation. 

Dissolved Oxygen 

* Automatic compensation oftemperature, salinity andairpressure. 

* A new dissolved oxygen electrode with the function ofsalinity measurement, can easily achieve automatic salinity compensation, short polarization time, fast response and accurate measurement. 

Ion Concentration

* 10options of common ions, the user can also set other ions. 

*Able to select or switch among four measurement units: pX,mol/L,mg/L andppm.
