Angle Caliper Helios 0374416-ISO calibrated ISO 400 x 230 mm 90°

The Helios angle caliper 0374416-ISO is a calibrated ISO reference tool with a fixed 90° angle and overall dimensions of 400 x 230 mm. It is intended for accurate layout, inspection and verification of right angles in metalworking, woodworking and quality control environments. Supplied with ISO-calibrated traceability, this angle caliper provides a stable reference for measuring and transferring perpendicularity where repeatable accuracy is required.

Advantages

The tool combines a rigid construction and a precisely machined 90° angle to reduce measurement uncertainty when checking or marking workpieces. ISO calibration ensures documented traceability for inspection records and laboratory use. Its 400 x 230 mm size offers a balance between coverage of larger components and manageable handling on a bench or in a measuring area.

Suitable for

• Inspection and verification of right angles in metal fabrication and machining
• Layout and marking tasks in woodworking and cabinetmaking
• Quality control checks in inspection laboratories and calibration rooms
• Setup and alignment of fixtures, jigs and machine beds

Key specifications

• Fixed angle: 90°
• Overall dimensions: 400 mm × 230 mm
• Calibration: Supplied calibrated to ISO traceable standards
• Construction: Rigid, machined reference faces for repeatable contact
• Application environment: Workshop and laboratory use for inspection and layout

How to use

Place the caliper so both reference faces contact the surfaces to be checked or used for marking. Ensure clean, debris-free contact areas and stable support beneath the tool to avoid tilt. For verification, use a dial indicator, test indicator or visual inspection along the edges to detect deviation from 90°. When transferring the angle for layout, hold the caliper firmly against the workpiece and scribe or mark along the reference face. Follow your internal procedures for handling calibrated items to protect the calibration certificate and traceability.

Usage recommendations

Store the caliper in a protective case or on a flat, vibration-free shelf when not in use. Avoid impacts and extreme temperature changes that can affect calibration. Periodically verify the angle against a known standard and return the tool for recalibration according to your laboratory or workshop schedule to maintain traceability and measurement reliability.
