VelociCalc Plug-In Probes
The plug-in probes allow users to make various measurements by simply plugging in a different probe that has the features and functions best suited for a particular application. Plug-in probes for the VelociCalc series can be ordered at any time and include a data sheet with a certificate of traceability. When it’s time for servicing, only the probe needs to be returned since all the calibration data is stored within the probe.
