ChronoMaster® Auto PRO
The compact, automatic microphone
- Change of test position
- automatic or manual
- Precise silent
- and smooth drive unit
- Connection with
- 1 cable via USB interface
The ChronoMaster Auto measures the beat noise of mechanical watches. It moves to all main test positions and any intermediate positions automatically and precisely. The movement in two axes is smooth and silent. It can measure while in motion and thus reveals new dimensions in the measurement of mechanical watches.
The high-quality drive unit was developed to fit the needs of the ChronoMaster Auto. The motors are stowed in the foot section of the device to prevent magnetic fields from affecting the function of the movement. The compact design with a low centre of gravity occupies little space and provides a high degree of stability. The ChronoMaster Auto requires a single USB cable for data connection and power supply for operation with a PC or the Witschi Terminal. Alternatively, the measurement data can also be transmitted wirelessly via Bluetooth.
