FEATURES
• Measuring head consists of a carbide tipped moving anvil and an interchangeable stationary anvil with a hardened steel ball
• Transmission lever system transfers movement of movable anvil to indicating instrument
• The broad centering bridge ensures automatic centering in the bore
• Resistant to temperature because the shank and transfer rod are made of heat resistant Invar steel
• Highly resistant to wear and tear because of carbide tipped moving anvil
• Constant measuring force due to built-in spring, eliminating user influence
• Universally applicable and extremely versatile - Each instrument spans a broad measuring range - Quick and easy to adjust to any size (within its range)
• Extensive modular system is composed of measuring head, holder, extensions, Right angle attachments and depth stops
• Invar steel has a particularly low expansion coefficient - instrument totally insensitive to any kind of heat (including user body heat and increased ambient temperature)
