Measuring amplifier «on a chip»
Thanks to the most advanced electronics, Metrohm has been able to reduce the measuring amplifier to the size of a postage stamp. This means that the complete measuring amplifier fits in the electrode cable head. It is automatically recognized and identified by its serial number.

Digital data transfer
Directly in the sensor, the analog/digital converter of the latest generation 854 iConnect converts the analog measuring signal into a digital data flow. Digital data transmission means that the measuring signal is no longer susceptible to electrostatic influences. Interference-free transmission can now always be guaranteed, no matter how long the electrode cable is.

Just take the measuring amplifier with you!
With the 854 iConnect, the sensor and measuring amplifier are always calibrated together, and the calibration data is stored in the intelligent electrode. As the measuring amplifier is no longer built into the instrument, the electrode and the 854 iConnect can be used together with different titrators.

iConnect and iTrode prevent you from using an

• incorrect electrode
• electrode whose calibration period or working life has expired

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 important electrode data, including part and serial numbers, calibration data, calibration history, working life and calibration validity period.

The electrode is identified automatically, and all its data is read automatically when the iTrode is connected to the 857 Titrando—eliminating mix-ups or editing errors. If the type of electrode is not the same as that defined in the method, then the iTrode will inform you and will prevent you from using it. In addition, monitoring functions do not allow the use of electrodes whose calibration data is outside the limits or whose calibration period has already expired.

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

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