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.

UNIDOS® Tango

Intelligent Detector Recognition

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.
Manage database.
Forget time-consuming manual data entries. To add or update detectors, simply tap the DMC icon in the detector database, then point the data matrix code on your calibration certificate at the device camera. The built-in scanner reads the code and automatically enters all detector-specific information.
Identify detector.
Ready to perform a measurement? Hold the data matrix code printed on the detector label in front of the device camera. The built-in 2D code scanner reads the code and calls up the correct detector simply by matching the data stored on the code to an entry in the detector database. Mismatches excluded.
A matter of seconds.
One code, one scan. Detector management and identification has never been faster, easier and safer.

Why Use IDR Technology?

Choose comfort

A scan is all it takes to keep your detector database up to date or identify the right detector. No manual entries or selections needed. Enjoy maximum ease of use thanks to automation.

Eliminate Errors

One mistype, and the wrong calibration factor is entered, or the wrong detector selected. By automating data entry tasks, IDR helps to avoid human errors and improve data quality.

Increase efficiency

IDR combines speed and accuracy. No need to type in data or search for your measurement detector in the detector database – it’s all in one code, and just one scan away.
