ISM pH Sensors

ISM stands for Intelligent Sensor Management. This is the name of METTLER TOLEDO's digital sensor technology. Most models of METTLER TOLEDO ISM ph sensors end with the letter "i".

METTLER TOLEDO ISM ph sensors offer a variety of predictive diagnostics that are designed to improve your maintenance and sensor replacement operations and reduce the risk for sensor failure. These include:

Dynamic Lifetime Indicator (DLI): Indicates to the user how many days remain until the sensor will need to be replaced. Unlike typical "counter-style" diagnostics, the DLI adjusts based on the conditions that the sensor is operating under. Proper maintenance can significantly extend the lifetime of sensors. 

Adaptive Calibration Timer (ACT): Tells the user how long until a sensor will need calibrated, based on the current measurement conditions. This is beneficial for switching from a periodic calibration scheme to a predictive calibration scheme, where you only calibrate your sensor when needed.

Plug and Measure is a technology on ISM ph sensors and other ISM sensors that enables faster startup and commissioning of a measurement point, and faster replacement of ISM ph sensors. Because these ISM ph sensors can store calibration relevant data on a chip in the sensor head, the sensor can be calibrated away from the process by using iSense software. A pre-calibrated ISM sensor can then be quickly put directly into the process without the need for another calibration at the measurement point. This is particularly beneficial at challenging measurement points or in hazardous or dangerous areas.

ISM Core is a software for METTLER TOLEDO ISM pH probes that dramatically simplifies calibration, maintenance and documentation. Using ISM Core software, you can calibrate intelligent ph sensors in a convenient location away from the process, automatically generate calibration reports, access all predictive diagnostics and counters (such as SIP or Autoclave counters), and assign sensors to their location for easy management of your entire ISM ph sensor inventory. This software also works with METTLER TOLEDO ISM digital dissolved oxygen sensors and digital CO2 sensors.
