The Mettler Toledo M800 Water 2-CH ProfiDP (4-Wire) is a two-channel, multi-parameter transmitter for water-system monitoring.
PROFIBUS DP communication supports integration with plant control networks, while the 5.7-inch color touchscreen provides a centralized interface for viewing measurements and configuring the instrument.
Designed for compatible ISM and flow sensors, the transmitter supports measurement parameters that include pH/ORP, conductivity, dissolved oxygen, dissolved ozone, TOC, and flow.

The ½ DIN polycarbonate enclosure has an IP66 protection rating and accepts either 100 V to 240 VAC or 20 V to 30 VDC power.
