Q45C4 4E Conductivity Water Quality Transmitter is the solution for almost any water-based process monitoring.

ATi’s 4-Electrode Conductivity Transmitter is the answer for water quality monitoring almost any water-based process. 

Drinking water, plating bath solutions, cooling water, process wash water, or virtually any other aqueous system can be monitored accurately and reliably. 

The unique drive/control scheme used in the 4-Electrode System allows a single sensor configuration to be used in conductivity ranges from 0-200 μS to as high as 0-2,000 mS (0-2 S).

ATi’s Q45C4 4-Electrode Conductivity Transmitter’s “auto-ranging” feature enables the monitor to display the actual conductivity value during “overshoot” conditions. 

For chemical mixing applications, a concentration display can be selected for a limited number of acids and bases. 

If your application involves very low conductivity/resistivity measurement, ATi can provide the Q45C2 system that is used in process waters with conductivities below 20 μS.
