Intelligent Detector Recognition

With its built-in camera-based 2D code scanner, UNIDOS Tango is the first electrometer to automate detector management and identification by using detector-specific data matrix codes and state-of-the-art scanning technology.

Updating your detector database or selecting the right measurement detector is now very easy and less error-prone: Simply scan the data matrix code on your calibration certificate or detector label with the device camera. No manual data entries needed. One code, one scan. IDR is particularly useful for clinical sites with multiple electrometers and/or detectors in use.

Individual user profiles

Individual user profiles

Reduce setup time and improve measurement consistency. Save your favorite device settings and detector parameters for frequent or specific measurement tasks, e.g., preferred measurement detector, user-defined correction factor and measurement range, as password-protected user profiles. A simple tap on the User Profile menu of your UNIDOS electrometer gives you immediate access to all profiles stored.

Full remote control (LAN/WiFi)

Full remote control capability

Hard-wired Ethernet or WiFi? Your choice. Connect your UNIDOS Tango to your local area network and control it remotely from your PC. Access its built-in webserver using any WiFi-enabled device – no app needed. Simply type its URL into a standard web browser and view measurement results directly on your smartphone or tablet from anywhere on site. As a smart electrometer with multiple connectivity options, UNIDOS Tango is incredibly easy and flexible in its operation.

Intuitive touchscreen

Intuitive touchscreen

The new UNIDOS generation is all about ease of use. It is the first to come with a capacitive touchscreen and a clean multi-lingual user interface, which gives you instant access to all relevant settings – in up to nine languages and with the simple touch of a finger. Measurement readings and other important data are always clearly visible on the main screen and from any viewing angle.

Instant access to data

Instant access to data

Readings are automatically saved to memory and can be instantly accessed with a single tap on the screen. Review the last 50 measurements and quickly calculate mean value and standard deviation right on the spot.

Versatile database

Versatile detector database

Efficiently manage up to 100 different detectors and their calibration data in one comprehensive, easy-to-access detector database. Ready-to-use detector templates make it easy for you to add and/or update detector-specific data with just a few mouse clicks.

Exceptional performance

Exceptional performance

As reference class electrometers that exceed IEC performance requirements, the new UNIDOS electrometers deliver fast, reliable and highly accurate results across all applications. Equipped with industry-leading amplifier technology, they are exceptionally stable and ready for use immediately upon start.

With the best available resolution (0.1 fA) in the market, the new UNIDOS Tango is your tool of choice for high-precision measurements, e.g., in small field dosimetry.


Intelligent Technology.

UNIDOS Tango comes with a built-in camera-based 2D code reader which automates detector management and identification. By using detector-specific data matrix codes and intelligent scanning technology, IDR saves time and eliminates potential error sources.

All in one code.

Each PTW reference ionization chamber is supplied with a calibration certificate which also contains a data matrix code (DMC). It stores the same information, e.g., the calibration factor and date as well as the name and serial number of the detector.


Best practice: PTW Track-it – Our clinical experience

Thu, Nov 25, 2021, 9:00 AM or 4:00 PM CET

How do you handle QA data management?

The documentation and management of QA data and reports is a time-consuming process which requires a lot of administrative work and ties up valuable resources in radiotherapy and diagnostic imaging departments.

Dr. Ashraf Esmail, Medical Physicist at the Leeds Teaching Hospitals NHS Trust, shares his journey of streamlining quality assurance management in clinical practice.

PTW Track-it – Our Clinical Experience

  • Introduction into evaluation of QA management systems
  • The implementation of track-it in our clinical departments
  • Clinical experience - how we use it
  • Future aspects

Pioneer Days

Invention of the ‘Electrostatic Relay”, a new revolutionary electromechanical component, by Dr. Wilhelm Hammer, associate physics professor, at the Physics Institute of Freiburg University. Hammer’s invention, which makes it possible to accurately measure radiation dose on X-ray therapy units, lays the foundation for the company’s success story.


To market the first dosemeter based on his invention, Hammer establishes his own company - Physikalisch-Technische Werkstätten. On 9 May 1922, the new company is incorporated. Its first registered address is Hammer’s private residence in Freiburg.
