MARAMETER 844 NB SELF-CENTERING DIAL BORE GAGE

MARAMETER 844 NB SELF-CENTERING DIAL BORE GAGE

Measuring head consists of a carbide tipped moving anvil and an interchangeable stationary anvil with a carbide 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

Measuring head consists of a carbide tipped moving anvil and an interchangeable stationary anvil with a carbide 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)
Invar steel has a particularly low expansion coefficient
– instrument totally insensitive to any kind of heat (including user body heat and increased ambient temperature)

MARAMETER 844 NR SELF-CENTERING DIAL BORE GAGE

Measuring head consists of a carbide tipped, movable measuring bolt and an opposing interchangeable stationary anvil with carbide ball
Stationary measuring bolt can pivot through 180°, giving rise to a very long return travel path of up to 40% of the measured bore
Movements of the measuring bolt are transmitted to the indicating instrument via the ring segment
The broad centering bridge ensures automatic centering in the bore
Resistant to temperature because the shaft and transfer rod are made of heat resistant Invar steel
Carbide tipped measuring contacts for high wear resistance
Constant measuring force thanks to built-in and independent measuring force spring preventing external interference
Universally applicable and extremely versatile
– Each instrument spans a broad measuring range
– Quick and easy to adjust to any size (within its range)
Invar steel has a particularly low expansion coefficient
– instrument totally insensitive to any kind of heat (including user body heat and increased ambient temperature)
