Features and Benefits

Strong in heavy-duty chemical applications

  • Made of chemically resistant PFA, this sensor shows no polarization, is insensitive to contamination, fouling or film formation on the sensor surface, extreme robust, easy to install and therefore suitable for a wide range of applications. The PFA version of the InPro 7250 is specially designed for operation in concentrated strong acids (oleum).

Compatible with METTLER TOLEDO's transmitters

  • METTLER TOLEDO transmitters offer a variety of advantages and benefits providing highest reliability, easy operation and advanced diagnostics. Amongst others, advanced software allows concentrations of a wide range of acids and caustic solutions to be displayed.
