Conducting maintenance for when it will truly be needed saves time and resources and supports compliance. That's what ISM's unique predictive diagnostic tools and software provide.

Now, with ISM™, you can clearly see the health of your sensors all the time. Our advanced predictive diagnostic tools show you how many days remain before calibration, part replacement, or sensor replacement will be needed.
And when maintenance is required, our ISM Core™ PC software guides operators step-by-step through the process.
ISM digital sensors help companies in the pharmaceutical, chemical, and food and beverage industries ensure process consistency. This short video looks at why ISM sensors are easy to maintain and manage:
Using a sensor's past and current exposure to process conditions, ISM diagnostics reliably predict when maintenance or calibration will be required. This allows planning of maintenance for exactly when necessary and reduces operating costs.
ISM Core software makes calibration significantly quicker and easier. The step-by-step user guidance reduces training efforts to a minimum. ISM Core enables calibration in a laboratory or workshop - away from any challenging environments. Calibrated sensors can then be stored and quickly swapped back into the process whenever needed.
Ensuring compliance with industry requirements is vital. ISM simplifies compliance because ISM sensors and ISM Core software hold a sensor’s maintenance history. Calibration reports and audit trails can be generated to Excel or as PDFs.
ISM ensures gapless and tamper-proof traceability of all calibrations, no matter whether the sensor was calibrated at the process or away from the process.
The diagnostics are sophisticated algorithms developed using METTLER TOLEDO’s many decades of experience of how analytical sensors are affected by process conditions. Sensor specific parameters, such as the characteristics of a pH sensor’s reference system and pH-sensitive glass, have been determined through extensive, long-term aging tests. Each sensor starts with a fixed lifetime in number of days. Depending on the process conditions a sensor has been exposed to, as well as the sensor’s current ‘health’, that lifetime will adjust. If the process conditions are harsh (e.g., constant high temperature) the lifetime will drop faster than for the same sensor used in a less harsh process. Using the information on process and sensor condition, the algorithms are also able to calculate how many days remain until calibration should be performed in order to restore measurement reliability, and when the sensor should be replaced.
In an analog analytical sensor system, the transmitter knows the correct value to display depending on the signal it receives from the connected sensor. So, when performing a calibration, it means that it is the transmitter that is being adjusted, not the sensor. In ISM systems, the calculation of the measurement is done in the sensor, not the transmitter. Also, the calibration data for the sensor is stored on its on-board microchip. This means an ISM sensor can be calibrated via the ISM transmitter it is connected to, a different ISM transmitter, or via our ISM Core software.
ISM Core is PC software that can be used for calibrating ISM sensors, performing other maintenance tasks, checking a sensor’s condition, maintaining a database of your ISM sensors, and generating reports on sensor maintenance for compliance purposes. Animations on ISM Core guide operators clearly through all maintenance steps.
