Display range of TH160
- D probe is for standard use.
- DC probe is short and is convenient in small space.
- DL type is used in confined surfaces such as gear wheels.
- D+15 type is for measuring in grooves or recessed surfaces.
- C type is used on surface-hardened, coated, thin-walled or
impact sensitive components.
- G type is used on heavy and rough cast and forged work pieces.
