Metrohm^® iTrode & iConnect

Intelligent Electrodes for Intelligent Titrators

The electrode used for a titration is one of the most important components of any system, and the iTrode and iConnect ensure that this critical component is working at its best

iConnect and iTrode prevent you from using an

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

iTrode

The built-in memory chip allows the storage of important sensor data, such as part and serial numbers, calibration data, calibration history, working life and calibration validity period. All the sensor data is read automatically when the iTrode is connected to the 857 Titrando. (link to 857). If the 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.

Since all the calibration data is stored in the chip, the electrode is transferable. It does not need to be recalibrated each time it is used with a different instrument. It is now possible to calibrate an electrode on one instrument and use it on another.

854 iConnect

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.
