Simple and straightforward in operation

The DuoSeries density measuring system consists of a scintillation detector and a sophisticated transmitter unit for display and operation. The density transmitter is a state-of-the-art control unit with robust 3.5” TFT touch panel, powerful Dual Core CPU, up to 4 calibration curves, compensation of product temperature variations via PT100 connected to detector or analog current input and diverse operator interfaces. The calibration parameters can be exported via the USB port and can be easily imported to devices at other measuring tags. Advanced self diagnostics and monitoring features ensure a safe function of the system. Furthermore the data logging functionality allows operators to analyse their processes in depth, e.g. develop trends, track process changes etc.
