Caliper digital INSIZE 1124-300A with 3V power, data output and 4 pairs of jaws

The INSIZE 1124-300A digital caliper is a precision measuring tool designed for accurate linear, depth and step measurements with a clear digital readout. It operates on a 3V power supply and includes a DATA output for transferring measurement results to compatible devices. The caliper is supplied with four pairs of interchangeable measuring jaws to cover external and internal measurements across a wide range, making it suitable for workshop, quality control and engineering environments.

Advantages

The caliper provides a high-contrast digital display that simplifies reading of values and reduces the risk of parallax errors associated with analog scales. The DATA output enables efficient collection and documentation of measurement results for quality control or statistical analysis. Interchangeable jaw pairs offer flexibility for measuring different workpieces without changing tools. The 3V power supply ensures reliable operation and straightforward battery replacement.

Suitable for

• Precision external diameter and length measurements in workshops
• Internal diameter inspection for quality control
• Depth and step measurements on machined parts
• Engineering prototyping and assembly verification

Key specifications

• Measuring functions: external, internal, depth and step measurements
• Measuring range: 0–300 mm (as implied by product model)
• Resolution: typically 0.01 mm digital display
• Power: 3V battery
• Data interface: DATA output for measurement transfer
• Accessories: four pairs of interchangeable measuring jaws

How to use

Before use, ensure the measuring faces and object are clean and free of debris. Switch on the caliper and zero the display with jaws closed. Select the appropriate pair of jaws for external or internal measurement and position them carefully against the workpiece. For depth or step measurements, use the depth rod and stabilize the tool perpendicular to the surface. Read the value on the digital display and, if required, transmit the measurement via the DATA output to a connected device according to the receiving equipment’s instructions.

Usage recommendations

Store the caliper in its protective case when not in use, avoid exposing it to strong magnetic fields or harsh chemicals, and replace the 3V battery promptly when the display dims. For consistent accuracy, calibrate the instrument periodically and handle the interchangeable jaws with care to preserve their measuring faces.
