0-1000mm / 0-40" Digital Caliper - 1135 Series (Insize)

The Insize 1135 Series Digital Caliper is a rugged stainless steel measuring workhorse designed for precision metrology and daily QC checks on the shop floor. It delivers fast, reliable external and internal measurements in a single instrument, ideal for fast-turnaround inspections and part-fit verifications.

• Dual jaws for external and internal measurements: Quickly switch between measuring outside diameters and inside bores without swapping tools, saving time on repetitive tasks.
• Wide range with fine resolution: 0–1000 mm / 0–40 in range supported by a precise 0.01 mm / 0.0005" resolution for tight tolerances and repeatable readings.
• Durable stainless steel construction: Built to withstand daily handling, cleaning, and routine wear, offering long-lasting durability and corrosion resistance in demanding environments.
• Practical controls for fast setup: On/off, zero, metric/imperial (mm/in), ABS (absolute) hold, and data preset enable quick, intuitive operation and repeatable measurements.
• Optional SPC data output with seamless integration: Cable code 7302-SPC5A enables direct transfer of measurements to your quality system, speeding data capture and reducing transcription errors; paired with a replaceable CR2032 battery for easy field maintenance.

The 1135 Series stands out by combining a rugged, dependable build with useful data features. The stainless steel body resists daily wear, while the dual jaws and high resolution give you confidence from quick prototype checks to strict tolerance validation. When your quality system demands traceable data, the optional SPC output bridges shop floor measurements with your data management software, streamlining reporting and audit readiness.

Ideal for routine part inspections along manufacturing and assembly lines, this caliper excels at quickly verifying both external dimensions and internal diameters of housings, enclosures, or machined fixtures. It’s equally valuable in prototype development, where fast, repeatable measurements accelerate design validation, and in quality assurance environments that require straightforward data capture and reporting.

Practical workflow tips: use the zero function to set a reference measurement for relative (comparative) fits, toggle between metric and imperial to match documentation, and enable ABS mode to preserve a stable reference after power interruptions. Activate the SPC output only when your quality system requires direct data transfer; otherwise, manual recording remains reliable and straightforward.

Frequently Asked Questions

What is the measurement range and resolution?
The caliper measures from 0 to 1000 mm (0 to 40 in) with a resolution of 0.01 mm (0.0005"). This enables precise readings within tight tolerances typical of precision metrology and quality control tasks.

Can it measure both external and internal dimensions?
Yes. The tool features dual jaws that allow quick external measurements and internal bore or hole measurements without changing tools, making it versatile for assemblies and fixture checks.

How does the SPC data output work and when should I use it?
The optional SPC data output uses cable code 7302-SPC5A to transfer measurements directly to your quality management system. Use it when you need traceable, audit-ready data without manual transcription; if your workflow doesn’t require direct transfer, you can simply record readings manually.

How do I maintain the caliper and replace the battery?
The caliper runs on a replaceable CR2032 battery, allowing quick field replacements with minimal downtime. Regularly inspect the jaws for wear, keep the scales clean, and store the instrument in a protective case to preserve calibration and accuracy.
