Indicating Plug Gage

FEATURES

• Measuring head has a hardened
chromium plated cylinder guide

and carbide tipped anvils
• The carbide expanding pin
transfers radial movement to

indicating instrument
• Constant measuring force as a

result of built-in spring,

eliminating user influence Application:
• Extensive modular system is
composed of measuring head, Standard model
holder, depth extension, Right • For rapid testing of diameter, roundness and conicity of bores
angle attachments and depth • Especially suitable for testing batches with tight tolerances

stops (for tolerances <10µm on request)
• Rocking in the bore is unnecessary to determine the reversal point
• Ideal for use in conjunction with digital display units and for subsequent
processing of measured values
