The iTrodes - electrodes with brains

The electrode used for the titration is really the most important component of any titration system, and until now it has been just this electrode that has formed the last gap in traceability. The 857 Titrando with iConnect now closes this gap and therefore guarantees complete traceability of the analytical result to each component participating in the analysis.

iConnect and iTrode prevent:

• the use of an incorrect electrode
• the use of an electrode whose calibration period or working life has expired.

The 854 iConnect is electrode cable and measuring amplifier in one. The iTrodes of the new intelligent electrode generation confirm Metrohm's leadership in the field of potentiometric titration.

The built-in memory chip allows the storage of such important sensor data as article and serial numbers, calibration data, calibration history, working life and calibration validity period.

All the sensor data are read in automatically when the iTrode is connected to the 857 Titrando. Mix-ups or editing errors are therefore eliminated.

The electrode is identified automatically. If the type of electrode is not the same as that defined in the method then the user is informed. This means that it is not possible to use an incorrect electrode.

Monitoring functions allow the exclusion of electrodes whose calibration data lie outside the limits or whose calibration period has already expired.

If the sensor is used with different instruments or if you wish to prevent inexperienced users from having to calibrate the electrode on their own instruments then the electrode can be calibrated on a different instrument under defined conditions. The calibration data stored in the chip make the electrode transferable; it does not need to be recalibrated each time that it is used with a different instrument.

The 857 Titrando is compatible with all existing sensors. Despite its new digital measuring interface and intelligent sensors, the 857 Titrando with combined analog and digital measuring amplifier (2.857.0020) also supports conventional sensors. This means that you can continue to use all your sensors.
