Dial Caliper INSIZE MDHC 50–100 mm measuring instrument

The INSIZE MDHC 50–100 mm dial caliper is a precision mechanical measuring instrument designed for routine dimensional checks and fitting tasks. It provides direct readout of linear dimensions via a dial indicator and supports external, internal and depth measurements within the 50–100 mm range. The compact, hand-held construction makes it suitable for use at workbenches, inspection stations and on-site checks where reliable, repeatable measurements are required.

Advantages

The dial indicator offers clear, analog readout for quick interpretation without relying on batteries or electronic displays. Robust metal components and a sliding guide deliver stable contact and consistent accuracy during repeated measurements. The tool’s compact form and moderate measuring range make it versatile for small-to-medium sized parts, while the mechanical design reduces sensitivity to electrostatic interference and eliminates the need for power sources.

Suitable for

• External diameter measurements of shafts, pins and machined parts
• Internal diameter checks of bores and holes
• Depth measurements of slots, steps and recesses
• Routine inspection and quality control in workshops
• Assembly and fitting operations requiring quick dimensional checks

Key specifications

• Measuring range: 50–100 mm
• Measurement types: external, internal, depth
• Display: mechanical dial indicator for direct analog readout
• Construction: metal frame with sliding jaws and depth rod
• Typical use: manual, hand-operated precision measurements

How to use

Place the caliper jaws on the object for external measurements, insert the jaws into a bore for internal measurements, or extend the depth rod into a slot to measure depth. Turn the fine-adjustment wheel or slide the carriage until the measuring faces make firm contact with the workpiece, then read the value on the dial indicator. Take several readings if necessary to confirm repeatability, and retract the jaws before moving the instrument to avoid damaging the measuring surfaces.

Usage recommendations

Handle the instrument with care, keep measuring faces clean and free of debris, and store the caliper in a protective case when not in use. Periodically check zero position and, if available, verify accuracy against gauge blocks or a calibrated standard. Avoid exposing the instrument to strong magnetic fields, heavy shock or corrosive environments to maintain long-term performance.
