The 891 Professional Analog Out is an analog output for intelligent IC instruments.
The «DSP» (Digital Signal Processing) supplies digital data which are converted into analog signals. These can be aquired by the external software by the respective interfaces.
The 891 Professional Analog Out comprises of 4 independent channels. Two of them are conductivity signals (e.g. from an anion / cation system). The other two may be used for different auxiliary data e.g. flow, pressure, gradient profile or temperature.
