Diatest Split-Ball Probe

Split-ball probes are universal bore gages for indicating internal measurements. The modular design with extensive accessories enables gaging of most common bores. This allows use for serial and individual control as well as preferentially in the plant directly at the production machine. Because of different styles, through bores, blind bores, parallel distances and others can be gaged.
