The M800 multi-parameter transmitter provides simultaneous monitoring of one, two, or four in-line sensors for measurement of pH/ORP, optical DO, amperometric oxygen (DO as well as O2 gas), conductivity, resistivity, TOC dissolved ozone, flow, and turbidity, in pure water as well as process applications.

ISM features available on all M800 models include Plug and Measure for fast sensor installation and start up, predictive maintenance information, and dynamic sensor lifetime status. Thanks to the iMonitor display, the condition of each sensor is determined at a glance allowing preventive action to be taken before processes are affected. The color touchscreen provides intuitive operation, with user selectable control and alarm management for challenging applications.

 

Simple operation through intuitive user interface
 
Thanks to the intuitive menus and touchscreen display, all operations from installation to system diagnostics are greatly simplified. Minimum training effort and easy handling ensure maximum convenience and minimum errors.
  

Lower cost of measurement point
 
One unit covers the whole range of major parameters for either process or water applications. Up to four sensors can be monitored with a single M800, significantly reducing installation costs and cost per measurement point.
  
Predictive diagnostics and improved maintenance management
 
The unique iMonitor concept allows you to monitor the actual status of every sensor at a glance and offers predictive maintenance information to improve maintenance management and avoid unplanned production shutdowns.
