The Model Q46CT Conductivity monitor/analyzer provides a versatile system for monitoring and control of conductivity over a range of 1 µS/cm to 2.000 Siemens/cm. 

The display may be programmed for ranges of 0-2000 uS, 0-2.000 mS, 0-20.00 mS, 0-200 mS, 0-2000 mS, or 0-2.000 S. 

A lower line display indicates the equivalent TDS value in mg/l, using a user programmable conversion factor. 

Q46CT monitors use a toroidal conductivity sensor that measures conductivity inductively. 

This type of sensor is particularly well suited to measurements in solutions that contain materials that would foul a normal conductivity sensor. It is very good for high conductivity measurements, but should not be used if normal conductivity is below 100 uS.
