Precision Pitch Measurement for Marine Propellers

The Pitchometer is a dedicated precision measurement system for inspecting the pitch and geometry of marine propellers, designed to support compliance with ISO 484 propeller standards and improve inspection consistency across shipbuilding and marine service environments .

Supplied by Innovative Measurement Technology, the Pitchometer enables accurate, repeatable measurement of key propeller parameters, helping manufacturers and repair facilities verify performance‑critical geometry with confidence.

Purpose‑Built for Marine Propeller Inspection

Propeller pitch directly influences thrust efficiency, vibration, fuel consumption and long‑term drivetrain performance. The Pitchometer is specifically engineered to evaluate these parameters in a controlled, structured measurement process, reducing manual interpretation and inspection variability .

The system supports precise evaluation of:

• Propeller pitch
• Blade rake (tilt)
• Angular deviation
• Axial position
• Propeller radius

This makes the Pitchometer an essential inspection tool for both new propeller manufacture and refurbishment.

Configurable Manual, Motorised & Automated Systems

The Pitchometer range is available in multiple configurations to suit different inspection requirements and production volumes:

• Manual Pitchometer with digital readout
• Motorised Pitchometer with PC‑based measurement software
• Fully automated Pitchometer with non‑contact laser measurement for maximum efficiency

Each system provides controlled movement through the radius, height and angular axes, enabling 360° measurement coverage across the propeller blade profile .

Structured Measurement & Digital Reporting

Pitchometer systems equipped with PC software enable automated data capture, analysis and reporting. Measurement results can be compiled into certificates of conformity, including propeller identification and customer data, supporting auditability and quality documentation where required .

This digital workflow improves traceability while reducing inspection and reporting time compared with manual methods.

Typical Applications

The Pitchometer is used by:

• Shipyards and propeller manufacturers
• Marine repair and overhaul facilities
• Propeller service centres
• Marine OEMs and classification‑driven inspection environments

It supports inspection during production, post‑machining verification and refurbishment workflows, where dimensional accuracy directly impacts performance.

Training & Application Support

To ensure effective deployment, pre‑testing and operator training are available, enabling users to gain confidence in both system operation and software‑based evaluation.

IMT provides application guidance to ensure the Pitchometer is configured correctly for propeller size, geometry and inspection requirements.
