M400 Process Transmitter
Reliable, Safe Process Control for Industrial Production
The M400 process transmitter family is a series of multi-parameter transmitters that features Intelligent Sensor Management (ISM) technology and covers pH/ORP, dissolved oxygen, dissolved CO2, dissolved ozone and conductivity. It offers a high-contrast touchscreen and four soft keys, allowing operation of the M400 in harsh applications without compromising user ergonomics. The M400 transmitter is also compatible with the GPro 500 gas analyzer for gas stream measurements.
Reduce Maintenance with Predictive Diagnostics on the M400
ISM diagnostics, including the Dynamic Lifetime Indicator, Time to Maintenance and Adaptive Calibration Timer, on the M400 offer true predictive maintenance, resulting in less unplanned downtime. Read more
Versatile Process Transmitter for Industrial Applications
The M400 multi-parameter transmitter is suitable for a range of liquid process measurements including pH/ORP, dissolved oxygen, dissolved CO2, dissovled ozone and conductivity measurements.
M400 Touchscreen & Buttons - Ideal When Wearing Gloves
The M400 offers a unique combined touchscreen and soft-key interface. This allows for easy operation of the M400 process transmitter, even in areas where gloves are required.
Operate in Hazardous Areas with the M400 2-wire
The 2-wire version of the M400 transmitter provides process safety in hazardous area environments. The M400 2-wire is ideal for chemical production.
M400 Offers Fast Startup with ISM Plug and Measure
When used with ISM sensors, Plug and Measure technology allows calibration of the sensor away from the process. The sensor can then be connected to the M400 with no further calibration needed.
Easy Integration of M400 Sensor Diagnostics & Sensor Data
The M400 transmitter offers HART and Foundation Fieldbus communication protocols, providing easy integration of sensor diagnostics and data into process control systems.
Data Capture and Setup With the USB Interface
The M400 offers an integrated USB interface that supports data logging, printer connection or up- and downloading of transmitter configurations.
Support & Repair
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.
The M400 can display 10 languages: English, German, French, Italian, Spanish, Portuguese, Russian, Japanese, Korean and Chinese (Simplified).
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.
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.
