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. Use the HART communication ability of the M420 transmitter series for your application.
     
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.
