Caliper INSIZE 300 Digital 12" (300 mm) ABS/Data, 3V battery, 150 mm jaws

Digital caliper INSIZE 300 (300 mm / 12") with ABS system and data output provides precise linear measurement for internal, external, depth and step dimensions. The instrument has a 300 mm measuring range and 150 mm jaws, powered by a 3V battery and equipped with an ABS (absolute) encoder to maintain position information when the unit is switched off. Data output allows connection to external devices for measurement logging and quality control workflows.

Advantages

The caliper combines a clear digital readout with ABS technology to prevent zero-loss errors after power cycles, ensuring stable readings. Its 150 mm jaws and 300 mm range deliver flexibility for a variety of workshop tasks, while the data output facilitates direct transfer of measurement values to computers or data collectors. A compact design and battery power make it portable and practical for both bench and field use.

Suitable for

• Measuring external diameters and lengths in mechanical workshops
• Checking internal bore dimensions and step depths
• Quality control and inspection with digital data logging
• Educational labs and technical training where accurate linear measurement is required

Key specifications

• Measuring range: 300 mm (12")
• Jaws length: 150 mm
• Measurement types: external, internal, depth, step
• Display: digital with ABS (absolute) encoder
• Data output: yes, for external connection and logging
• Power supply: 3V battery
• Material: durable metal sliding frame with precision-ground measuring faces

How to use

Before use, check the battery and zero the caliper on fully closed jaws or use the ABS zero function to ensure correct reference. Place the jaws on the workpiece for external or internal measurements, slide the carriage until the measuring faces contact the surface, and read the value from the digital display. For depth and step measurements extend the depth rod or use the jaw faces accordingly. Use the data output to connect to a computer or data logger when measurement records are required.

Usage recommendations

Handle the caliper with care to protect the measuring faces; avoid exposure to excessive dust, oils or liquids. When not in use, store the instrument in a protective case and remove the battery if it will be unused for extended periods. Periodically verify accuracy with gauge blocks or certified standards and calibrate according to workshop or quality management procedures.
