Analog controller to measure conductivity
User-friendly, analog field monitor - suitable for numerous conductivity measuring cells due to different measuring ranges and cell constants:
•For versatile applications with 7 selectabel measuring ranges
•connection of different measuring cells possible
•User-friendly operation thanks to clear menu structure
The LF 298 is an economical and metrologically flexible solution for use in the field. Galvanically isolated outputs are just as much standard as a complete function monitoring of the monitor and the connected sensor.
