•Datasheet: M420 (2-wire Transmitter, For pH, O2)
•Datasheet: Operation Manual: M420 (2-wire Transmitter, For pH, O2)

The M420 transmitter series stands for reliability in loop-powered applications. When your process requires the highest safety level for pH and oxygen measurement, the M420 brings you the best performance and the advantages of the state-of-the-art ISM technology for efficient maintenance.

Features and Benefits

• Reliability by design
  The M420 transmitter development was focused on rugged design and resistance to the most difficult operation conditions. This allows the M420 to stand out for its superior operational reliability in chemical, pharmaceutical or gas phase oxygen applications.
• Versatility thanks to mixed-mode input
  Available for a whole range of measurement parameters, the M420 is compatible with both conventional and ISM sensors.
• Additional functionality for greater flexibility
  Configure your M420 to better suit your process needs. Add a second analog output or select the extended logbook, 21 CFR Part 11 conformity with AuditTrail™ or trace oxygen measurement.
• One step ahead of maintenance
  Stay ahead of your maintenance tasks with the ground-breaking Intelligent Sensor Management (ISM) Technology from METTLER TOLEDO. ISM-equipped measurement loops are efficient to maintain without compromising on your process reliability.
• Predictive maintenance thanks to ISM technology
  Thanks to the ACT (Adaptive Calibration Timer), calibration intervals for each measurement loop can be flexibilized, based on the real-time sensor information and current process conditions.
