Model M800 - Multi-Parameter Transmitter



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, 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.
