Mettler Toledo M800 Transmitter

Home / Products / ANALYSERS / ANALYSER AND TRANSMITTER / Mettler Toledo M800 Transmitter

Multi-Parameter, Multi-Channel Transmitter

Touch the Future

for pH, Oxygen, Ozone, Flow, CO2, Conductivity, TOC, Flow and Turbidity

Intelligent and intuitive

The M800 transmitter series features premium Intelligent Sensor Management (ISM®) technology measuring

pH/ORP, optical DO, amperometric and optical Oxygen (DO as well as O2 gas), Dissolved Carbon Dioxide,

Conductivity and in some models – Dissolved Ozone, Total Organic Carbon (TOC) and Flow. The multi-parameter

transmitter accepts any compatible combination of sensors. In addition to this the mixed-mode

capability of the M800 1-channel allows the connection of analog or digital ISM sensors. Up to 4 channels

of process measurement provides immediate Plug & Measure installation and operation, predictive sensor

maintenance and dynamic lifetime status. Thanks to iMonitor, the maintenance conditions of the measuring

loop are observed and displayed comprehensively for preventative action. The color touchscreen ensures

intuitive operation, with user selectable control and alarm management for complex applications.
