NOMEX Dosemeter

OVERVIEW

  • 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)
