Topdon unveils One Pro at Automechanika
Topdon has placed two of its latest diagnostic technologies at the heart of its Automechanika Frankfurt 2026 presence, with the European debut of the new One Pro and the TC001 Max portable thermal imaging system both taking centre stage at the show.
The One Pro is the flagship model in Topdon’s new six-tier One diagnostic range, which also comprises the OneE Nano, One Mini, One, One Lite and One Plus. Designed for independent workshops and automotive specialists, it combines extensive vehicle coverage with advanced diagnostic, coding and programming functions designed to help technicians work more efficiently across an increasingly complex vehicle parc.
Supporting more than 100 vehicle brands, the One Pro provides ECU programming across all vehicle systems, alongside ECU coding and one-click customisation for more than 10 vehicle brands. Its graphical diagnostics and live data stream fusion capabilities are designed to give technicians a clearer view of vehicle information, combining multiple data streams to help identify faults faster and make informed repair decisions.
The platform also features advanced OE topology mapping, more than 50 hot maintenance services, and access to FCA, Renault, Nissan and VAG SFD security gateways. Its One VCI Pro supports J2534 Pass-Thru, while vehicle information retention helps eliminate the need to repeatedly identify the same vehicle during diagnostic work.
Further features include support for battery testing, borescope and oscilloscope functionality, bringing a broad range of workshop tools together within a single diagnostic platform.
The One Pro is powered by an 8-core, 2.2GHz processor and runs Android 16.0, with 8GB RAM and 256GB storage. Its 12-inch, 1280 × 800 display is supported by a 15,000mAh battery and 16MP front and rear cameras, providing a robust platform for extended workshop use.
Oscar Diaz, CEO, Topdon Europe, commented: “Vehicle technology is changing rapidly, and independent repairers are facing increasingly sophisticated systems, more complex electronics and greater demands on their diagnostic equipment.
“We launched the One Pro in response to that shift – not simply to add another diagnostic tool to the market, but to give technicians a platform that brings together the depth of functionality, vehicle coverage and efficiency they need to deal with this changing environment. Its features have been specifically designed to help workshops operate more effectively and with greater confidence.”
Alongside the One Pro, Topdon is showcasing the TC001 Max, its dual-lens portable thermal imaging system, which has been named an official nominee for the Automechanika Innovation Awards 2026 from 185 international entries.
The TC001 Max combines a 256 × 192 infrared sensor, enhanced to 512 × 384 through Topdon’s TISR super-resolution technology, with a visible-light camera. This enables technicians to produce clearer thermal images and identify temperature variations across a range of automotive, electrical, HVAC and mechanical inspection applications.
