FAQs

What is the M400 transmitter?

The multi-parameter M400 transmitter series features Intelligent Sensor Management (ISM) technology and covers pH/ORP, oxygen (for measurement of dissolved oxygen or in gas), dissolved CO2, dissolved ozone, conductivity or the GPro 500 TDL series of gas analyzers, depending on the type you choose.

Which ISM features are available on the M400?

The M400 gives access to all ISM features when integrated with a digital ISM sensor. With tools such as the Dynamic Lifetime Indicator, Time To Maintenance and Adaptive Calibration Timer, ISM technology on the M400 offers true predictive maintenance, resulting in fewer unscheduled shutdowns. The M400 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.

How many languages is the M400 available in?

The M400 can display 10 languages: English, German, French, Italian, Spanish, Portuguese, Russian, Japanese, Korean and Chinese (Simplified).

Can the M400 be used for process gas measurements?

The M400 offers options for process gas measurements with the GPro 500 tunable diode laser gas spectrometer. This allows the measurement of gas-phase oxygen, CO, moisture, ammonia, methane and more process gas measurements for safety and corrosion prevention.

What are the different versions of the M400?

There are multiple versions of the M400 transmitter. The M400 Type 1 transmitter is designed for chemical production. The M400 Type 2 is designed for pharmaceutical processes, and the M400 Type 3 is designed for the integration of gas-phase analysis. METTLER TOLEDO produces a 4-wire version of the M400 and a 2-wire version for hazardous areas. Your local METTLER TOLEDO sales representative can help you choose the M400 that is best suited to your application.
