Witschi QuartzSensor® Quartz Watch Tester - HT74-PRO

QuartzSensor Pro, the efficient measurement of closed quartz watches

Compact measuring device for the measurement of analogue and digital quartz watches, as well as tuning fork watches in closed condition and with inserted battery. The sensitive capacitive and inductive sensors measure the rate deviation and analyse the motor pulses. Sophisticated shielding of the sensors minimises unwanted interference.

User-friendly device is connected to a Windows PC or the Terminal via the USB interface. The stable stand enables comfortable work with movements and watches with or without wristband and is cushioned to prevent scratches. Automated measurement sequences with WiCoTRACE

In the parameter and measurement result management software WiCoTRACE, automated measurement sequences can be easily created and centrally managed.

The user-friendly application in WiCoTRACE supports an efficient test process.
