Digital inside groove calipers with flat points – SA290

The digital inside groove calipers with flat points is a measuring instrument designed for workshop and quality control applications where it is necessary to measure internal diameters only with greater accessibility and reliability.

Equipped with dedicated flat points for internal measurements, it allows measurements even in areas difficult to reach with standard jaws, making it particularly useful for grooves, seats and cavities.

Manufactured in stainless steel, it guarantees robustness and long-term stability even in continuous use. The LCD display provides a clear and immediate reading of values.

The 0.01 mm resolution and mm/inch conversion allow fast and accurate measurements of internal diameters, improving dimensional inspection reliability.

Thanks to the configuration with flat points for internal measurements, this caliper is particularly suitable for inspections on components with complex internal geometries where traditional calipers are limited.

Applications

• Measurement of internal diameters with dedicated flat points
• Inspection of grooves, seats and cavities
• Dimensional inspections on components with difficult internal geometries
• Quality control in workshop and production

FAQ – Digital inside groove calipers with flat points

When should a caliper with flat points for internal measurements be chosen instead of a standard caliper?
When the dimensions to be inspected are located in poorly accessible internal areas where traditional jaws are not suitable.

For which components is this type of caliper recommended?
It is particularly useful on components with internal grooves, seats, cavities and geometries where the measuring point cannot be reached with traditional instruments.

Why are flat points for internal measurements useful in dimensional inspection?
Because they improve access to the inspection area and allow more direct measurement of specific internal dimensions.

Can this caliper also measure external dimensions?
No, it is an instrument designed specifically for internal diameter inspection, therefore it is chosen when the application is focused exclusively on this type of measurement.

In which industrial contexts is it most commonly used?
It is commonly used in mechanical workshops, quality control and production, when internal dimensions on machined components must be inspected.

Is it suitable for repetitive inspections in production?
Yes, it can also be used for repetitive inspections, especially when internal dimensions on series production parts must be checked frequently.

What is the advantage compared to other internal measuring instruments?
It offers immediate reading and practical measurement management, making it useful when internal diameters must be checked quickly and with good operational continuity.

On which geometries is it most advantageous?
It is particularly advantageous when the internal dimension is located in restricted areas, grooves or cavities where accessibility is critical.

Can it be a good solution for quality control?
Yes, it is an interesting solution for quality control when internal dimensions must be verified with a dedicated instrument.

Why choose a caliper dedicated only to internal measurements?
Because in some applications a specialized instrument allows more efficient work, reducing the accessibility limits typical of generic models.
