Digital Caliper INSIZE 22–150 mm model 1120-150A

Digital caliper INSIZE 22–150 mm model 1120-150A is a precision measuring tool designed for internal, external and depth measurements. It covers a measuring range from 22 to 150 mm and features a clear digital readout that simplifies reading dimensions of parts, shafts, holes and assemblies in workshop, inspection and quality-control environments.

Advantages

The caliper provides rapid numeric readout with high resolution for reliable size checks. Its hardened measuring jaws offer durability and stable contact when measuring metal and non-metal components. The instrument includes a zero-setting function and metric display for straightforward operation and repeatable measurements. Its compact form and smooth sliding action make it convenient to handle during repetitive tasks.

Suitable for

• External diameter measurements of shafts, bolts and profiles
• Internal diameter measurements of holes, bores and cutouts
• Depth measurements for steps, slots and recessed features
• Workshop layout, part inspection and quality control

Key specifications

• Measuring range: 22–150 mm
• Measurement functions: external, internal and depth
• Display: digital readout for direct numeric values
• Resolution: fine resolution suitable for workshop metrology
• Construction: hardened measuring jaws and rigid beam for stability
• Operation: zero-setting capability and simple measurement transfer

How to use

Before measuring, clean the measuring faces and the workpiece to remove chips and debris. Slide the jaws gently to the required position and close them until they make light contact with the surfaces to be measured; read the measurement directly from the digital display. For internal measurements, insert the internal jaws and expand until they contact the bore; for depth measurements, use the depth rod and slide the main beam until the rod reaches the bottom of the feature. Use the zero function to set a reference point for differential measurements.

Usage recommendations

Store the caliper in its protective case when not in use, avoid exposing it to liquids or strong magnetic fields, and periodically verify accuracy against gauge blocks or reference standards. Replace the battery promptly when the display dims to ensure consistent readings.
