Internal Micrometer (Inside Micrometer) — Digital, IP65, Microtech Metrology
The internal micrometer is a precision instrument for measuring internal diameters and bores in production and quality control, optimised for large ranges and workshop conditions.
- Digital readout with 0.0001 mm resolution
- ISO 17025 calibrated with certificate
- IP65 protection for harsh environments
- Measuring range 125–4000 mm with extensions
Precision for wide-range bore inspection
The instrument combines a high-resolution digital display with a reading of 0.0001 mm, enabling clear, repeatable readings across extensive diameters up to 4000 mm. The specified accuracy ±0.04 mm provides a predictable tolerance band for pass/fail decisions in routine quality checks, reducing rework and inspection time. This performance is particularly valuable when checking bearing housings, large sleeves or assembled components where reliable internal diameter control improves downstream assembly yield and machining cycles.
Robust construction and certified traceability
Built to withstand workshop environments, the device meets IP65 protection against dust and water jets, which preserves electronics and mechanics during everyday use. Calibration is supplied in accordance with ISO 17025, and a traceable calibration certificate accompanies the instrument, ensuring measurement results are accepted in formal inspection processes. For procurement and audit purposes this certificate simplifies incoming inspection and supports quality management systems.
Adaptable measuring range with practical extensions
The basic measuring range of 125–4000 mm can be extended using supplied extension rods: 25, 50 (2 pcs), 100 (2 pcs), 200 (2 pcs), 400 (8 pcs). This modular approach keeps the primary instrument compact on the bench while allowing rapid configuration for very large bores. The measuring head diameter of 22 mm provides a stable contact geometry that helps reduce radial deflection during insertion and measurement in deep bores.
Efficient handling and clear results
Electronic measurement is driven by an integrated control that provides stable readout and straightforward operation. The digital interface and robust mechanics minimise operator influence on results, while the instrument’s repeatability supports fast throughput in serial inspection. Fewer ambiguous readings and a durable build translate into lower downtime for calibration and maintenance, supporting continuous production schedules.
