M300 Process & Water Transmitters

The M300 is a multi-parameter transmitter available in one- or two-channel models. All models (¼ DIN and ½ DIN) accept analog sensors or digital ISM sensors, providing a truly flexible solution. High versatility and reliability make the M300 transmitter the ideal choice for your basic process and water applications.

The M300 can be integrated with sensors that measure pH/ORP, resistivity, conductivity, dissolved oxygen and dissolved ozone.

The M300 can display 10 languages: English, German, French, Italian, Spanish, Portuguese, Russian, Japanese, Korean and Chinese (Simplified).

The M300 gives access to all ISM features when integrated with a digital ISM sensor. This includes the Dynamic Lifetime Indicator (DLI), which gives a predictive indication of remaining sensor life, the Adaptive Calibration Timer (ACT), which uses process conditions to diagnose when a calibration will be needed. The M300 also has Plug and Measure, which allows you to hot-swap a sensor by calibrating it away from the process and then quickly implement it into the process without the need for calibration at the measurement point.

The M300 transmitter comes in two main model types: the M300 Process and the M300 Water. The M300 Water is a transmitter primarily for pure water monitoring, with a focus on pharmaceutical waters, power plant water/steam cycle and semiconductor ultrapure water. The M300 Process is a transmitter primarily for liquid process measurements in chemical production, food and beverage production, waste water and other industrial processes.

The M300 is easy to set up via the streamlined menu structure. For companies that need to set up multiple M300 transmitters, METTLER TOLEDO offers a Transmitter Configuration Tool with which you can build the transmitter configuration on a PC and then transfer it to multiple M300 transmitters via USB.
