INSIZE 1178-300P Digital Inside Groove Caliper | 33–300mm

The INSIZE 1178-300P Digital Inside Groove Caliper is a specialized measuring tool designed for inspecting internal grooves, recesses, and other hard-to-reach internal features. Its purpose-built measuring design provides a practical way to check groove dimensions on machined components where a conventional caliper may not provide adequate access.

With a 33–300 mm / 1.30–12" measuring range, ±0.05 mm accuracy, and 0.01 mm / 0.0005" resolution, the 1178-300P is well suited for precision dimensional inspection in machine shops, manufacturing, and quality-control environments.

Key Features

• 33–300 mm / 1.30–12" measuring range

• ±0.05 mm accuracy

• 0.01 mm / 0.0005" resolution

• Specialized design for inside groove measurement

• Digital display for quick, direct readings

• No data interface for a straightforward inspection setup

• Designed for measuring internal features that are difficult to access with standard calipers

Specialized Inside Groove Measurement

The 1178-300P is designed specifically for measuring internal grooves and recessed features. Its specialized measuring geometry allows the instrument to reach internal surfaces and provide a direct dimensional reading.

This makes it useful for inspecting machined components where groove dimensions need to be verified against engineering drawings or production specifications.

300 mm Measuring Capacity

With a maximum measuring range of 300 mm / 12", the 1178-300P provides substantially more capacity than conventional handheld digital calipers.

The 33 mm minimum measuring range makes this configuration appropriate for larger internal grooves and recessed features.

Digital Measurement

The 1178-300P provides 0.01 mm / 0.0005" resolution and ±0.05 mm accuracy, allowing operators to obtain precise digital readings during dimensional inspection.

The direct digital display makes measurements easy to read during repetitive inspection tasks.

Simple Inspection Configuration

Unlike the standard 1178-300, the 1178-300P does not include a data interface. This makes the 1178-300P a straightforward choice for applications where measurements are read directly from the display rather than transferred electronically.

Applications

The INSIZE 1178-300P is suitable for:

• CNC machining inspection

• Internal groove inspection

• Recess measurement

• Precision machining

• Machine shop quality control

• Production inspection

• Incoming inspection

• Metalworking

• Industrial component inspection

• Dimensional quality control
