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.
