The Dose-1 is a high-precision reference class electrometer that significantly exceeds the recommendations of the IEC 60731 and the AAPM ADCL’s. It is suitable for the use with ion chambers, semiconductors and diamond probes. The DOSE-1 is ergonomically designed and intuitively easy to use. The standard DOSE-1 connects to either TNC or BNC connector types. Optionally , the DOSE-1 is compatible with TNC, BNC, M-type and BNC/banana connector types.
• Large, high contrast graphic electro luminescent display with a wide viewing angle for complete and comprehensive display of all measured values, chamber and correction factors on the main screen.
• Dose, dose rate, average rate, charge, current and dose per monitor unit are all measured and displayed simultaneously in the expanded screen.
• Time base for the dose rate is selectable prior to or after the measurement. The selectable units are: second, minute and hour.
• The operator interface is ergonomically designed and intuitively easy to use with pop-up menus, operated by soft keys.
• Storage of up to 40 detector specific data sets in a sensor library, including physical and geometrical parameters.
• Built-in electrical check source as well as leakage and bias voltage testing to ensure maximum reliability and accuracy.
• The DOSE-1 has a wide range power supply for automatic adoption to mains voltage worldwide. Battery operation with 4 D cells or NiCad rechargeable batteries is optionally available.
