MaraMeter 844 Dks

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, Application:
eliminating user influence
• Extensive modular system is Model for blind holes

composed of measuring head, • For measurements close to the base of the hole
holder, depth extension, Right • For the 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
