NOMEX Dosemeter
- CE marked, class IIb certified diagnostic dosimetry system, fully compliant with IEC 61674 for acceptance testing and quality control measurements on RAD, FLU, DENT, CT and MAM X-ray modalities
- Field-class electrometer acc. to IEC 60731 for air kerma measurements in radiotherapy and orthovoltage therapy
- Outstanding accuracy (± 2%) and excellent resolution (20 fA)
- Connection of semiconductor detectors or ion chambers or of the NOMEX® Multimeter
- Combined with the NOMEX Multimeter and/or NOMEX mAs all relevant QC parameters can be captured in one single shot
- Automatic air density correction when using ion chambers
- Waveform display and storage of last 100 measurements
- Allows data and waveform export as XLS, XML or CSV file via USB or Bluetooth®
- Operation menu in multiple languages (Chin./Eng./Fren./Ger./Ital./Jap./Port./Russ./Span.)
- Convenient firmware updates on-site
- 100% precision
Outstanding Precision and Excellent Resolution: The NOMEX® Dosemeter comes electrically calibrated with an intrinsic error of max. ± 2%. Measuring results of highest accuracy and of a superior reading resolution (20 fA) are guaranteed. - 100% ease of use
Connect the detector of choice (usage of already available PTW diagnostic detectors!), position the detector and start the measurement. - Sophisticated Warning and Error Management
NOMEX® displays when a measurement is inaccurate and suggests what to change within the settings or the measurement setup. - Time-Saving, Straightforward and Cost-Effective Service and Calibration Workflows
Firmware updates can be easily performed via USB connection to a PC. No need to return the device to the manufacturer. PTW devices are worldwide well-known for their reliability, reproducibility and long-term stability. A recalibration is recommended only every 2 years.
- Individual sets for every X-ray modality available: Different NOMEX sets with or without the NOMEX Multimeter and each with or without mAs option are available!
- Service contract for NOMEX® Dosemeter (Bronze, Silver, Gold)
