    Version history – innovations

    •V1.06: Minor general optimizations

    •V1.05:
    ?The FDO®925 can be operated with an adjustable t90 response time function.
    This function allows the adaptation of the response time of the FDO 925® to the application, e.g. measurement in an aeration tank, checking of online sensors.
    ?Optimized digital communication
