Advanced MODULAR benchtop meter, allows the simultaneous use of 4 equal or different modules. The possible modules are:

pH/Temperature:

- Up to 5 calibration points with automatic recognition of USA/NIST and DIN standards.

- Correction of calibration errors without recalibration with the edit function.

pH/Ion concentration/Temperature:

- All the benefits of the pH module.

- Advanced functions for ion concentration measurement: selective electrode identification, auto-whitening, isopotential, stability.

- Incremental methods: known addition, known subtraction.

Conductivity/Salinity/Resistivity/TDS/Temperature:

- Selectable reference temperature: 5,10,15, 20 or 25ºC.

- Temperature correction: linear, non-linear, or

Dissolved oxygen/RDO/Temperature:

- Automatic temperature compensation.

- Salinity compensation.

- Barometric pressure compensation (automatic or manual).

The calibration is stored in the module itself.

Color display with:

- Real-time graphics - Alarms and indicators on screen.

- User selectable display settings.

- Numeric keypad. - Easy communication with computer: RS232 output, two USB ports. - Simultaneous display of all modules connected to the equipment. - Non-volatile memory, stores up to 2000 readings referenced with date and time. - Includes analysis software to transfer stored results or readings on screen in real time.
