Caliper INSIZE 4834-1 measuring range 0–6 in / 0–150 mm dial type

The INSIZE 4834-1 caliper is a manual precision measuring instrument with a measuring range of 0–6 inches (0–150 mm) and a dial-type readout for incremental measurements. It combines hardened jaws for reliable external and internal dimension checks, a depth probe for depth and step measurement, and a sliding main scale for quick positioning. The instrument is designed for routine workshop use, quality control tasks and engineering checks where clear, direct dial indications and straightforward operation are required.

Advantages

The dial readout provides immediate incremental readings without reliance on batteries or electronics, making it suitable for environments where durability and simplicity are important. Hardened measuring jaws resist wear during repeated use and maintain accuracy over time. The integrated depth probe and step measurement capability expand the caliper's functionality beyond simple external and internal measurements. The construction and scale markings support repeatable manual measurement procedures common in inspection and maintenance workflows.

Suitable for

• Workshop dimensional checks on machined parts
• Quality control sampling and inspection
• Engineering prototyping and manual measurement tasks
• Maintenance and repair operations requiring quick, portable checks

Key specifications

• Measuring range: 0–6 in / 0–150 mm
• Readout type: dial indicator (incremental)
• Measuring jaws: hardened for external and internal dimensions
• Additional probe: depth/step measuring blade
• Scale: engraved main scale for coarse positioning
• Typical accuracy class: precision manual caliper level suitable for workshop use

How to use

Position the caliper jaws around the external feature or inside the bore for internal checks, then close the jaws gently until contact is made and read the value from the dial and main scale. For depth measurements, extend the depth probe into the hole or past the step and read the dial indicator. Ensure the measuring faces are clean and aligned with the measured surface. Use the sliding thumb wheel or screw stop if present to obtain steady contact before reading. Zero the dial at a reference point if comparative measurements are required.

Usage recommendations

Handle the caliper carefully and store it in a protective case when not in use. Keep measuring faces clean and free of debris; wipe with a lint-free cloth before each measurement. Avoid exposure to strong impacts, moisture, or corrosive chemicals. Periodically check calibration against a gauge block or reference standard to maintain measurement reliability.
