Usages:
The Universal Length Measurer （ULM）is a kind of length measuring instrument integrated fine mechanics, optical system and electrical parts into an organic whole. This instrument is used for direct measurement and comparative measurement for dimensions of parts and components and makes special-purpose extra-equipment to the instrument carry out various special measurements. The scope of uses is as follows:
External dimensions
The measurement of the parallel plane for the measured piece, such as: measuring blocks;
The measurement of the spherical dome for the measured piece, such as: length bars, steel balls;
The measurement of the cylindroid for the measured piece, such as: circular cylinders.
Internal dimensions
The measurement of the parallel plane for the measured piece, such as: snap-gauge;
The measurement of the aperture, such as: ring-gauges.
Screw thread
The measurement of external and internal effective diameter of threads.
Comparative measurement
The large-or-small movable measuring hooks are used to conduct comparative measurements for internal and external dimensions.
Measuring range (mm):
External size:
Absolute measurement: 1-100
Comparative measurement: 0-670
Internal size:
When using small measuring hook
(maximum insert depth 12, maximum wall thickness 50): 10-400
When using large measuring hook
(maximum insert depth 50, maximum wall thickness 85): 30-370
When using electronic measuring hook: 1-60mm
When using universal measuring hook: 14-112mm
Measurement of internal thread mid-diameter:
When using small measuring hook (thread small diameter 13-30mm)
When using large measuring hook [thread small diameter 31 ~ (70 wall thickness) X 2
Thread distance: 0.5~6 mm
Measurement of external thread mid-diameter: maximum 200mm, thread distance 1~6 mm
Measuring force (N): 0, 1.5, 2.5
