Product Description
JD25-D / JD25-C Digital Universal Length Measurer

Digital universal length measurer is a kind of length measuring instrument which is used in absolute and comparative measurement. It is mainly used in metal-processing industry, especially those measuring rooms or inspection stations of machinery industry and others industrial fields, such as tool-measure and instruments manufacturing.

1. High quality cast-iron base support, it has a good stability after long-term natural seasoning.
2. Optimization design, make sure the structure with high performance and precision.
3. Various kinds of accessories are provided, so it has good universal performance.
4. It is equipped with optical grating measuring system, the measuring result is displayed in number visually.
5. The illumination system of optical grating adopts infrared illuminator which is low voltage and current, small volume and long life.
6. It uses Abbe's principle and high precision measuring system, so it has a high measuring precision.

Main Measure Work-pieces Include:
1. Smooth columniform worpieces (Axis, hole, plug gauge and ring gauge etc )
2. The MID-diameter of internal thread, external thread, thread plug gauge and thread ring gauge
3. Workpieces with parallel plane (calipers, length bar and low-grade measuring block)

Technical Parameter:
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
Digital resolution: 0.1um
Accuracy repeatability of the instrument:
. External-size measurement 0.3μ M
. Internal - size measurement 0.5μ M

Accuracy of instrument:
While direct measurement of external size, accuracy of instrument is superior to
(0.5 + L/200) um for JD25-D and 0.5 um for JD25-C
While measurement of internal size, accuracy of instrument is superior (1 +L/100) um JD25-D and 1 um for JD25-C

Universal worktable:
