Easy maintenance:

Nonperforming electrodes;
Built-in program self-diagnosis.
lack of setup and adjustment procedures.

Ease of use:

The single reagent system for any combination of measured parameters.

Automatic 1 and 2 point calibration, rinsing, air in the control sample, the presence of the reagents and condition of the measuring system.

Ease of use it provided all third control keys and menus displayed on the LCD display;

Sampling of any laboratory glassware;

Plug the drain container it eliminates the possibility of operator exposure.

«Stand by» mode provides always ready to work.


Term of service electrodes – more than 1 year.

Quality control:

Memory on 30 measurements control samples3 levels .

Software determination of the values X, SD and CV%based on results stored in the memory of the control sample measurements.

Printer Output quality control diagram30 days of.

«Stand by» mode eliminates device failures as a result of long-term downtime;


Discrete replacement of reagents as they are spending.
