Digital Caliper INSIZE 300 mm IP67 ABS/SQ 12 3V with Roll Case — model 1118-300B

INSIZE 300 mm digital caliper model 1118-300B is a precision measuring tool designed for external, internal and depth measurements up to 300 mm. The instrument features a clear digital readout, an absolute (ABS/SQ) measurement system and an IP67 protection rating for water and dust resistance. Supplied with a 3V battery and a roll case for safe storage and transport, this caliper is intended for workshop metrology, quality control and general precision measuring tasks.

Advantages

The ABS/SQ absolute measurement system provides a stable zero reference without the need to reset when switched on. IP67 protection ensures reliable operation in environments with dust and occasional water exposure. The digital display offers rapid, easy-to-read measurements in metric or imperial units, while the included roll case protects the instrument during storage and transport.

Suitable for

• External diameter and length measurements

How to use

Before use, ensure the measuring faces are clean and the battery is installed. Switch the caliper on and, if required, set the display to the preferred unit (mm or in). For external measurements, place the jaws around the object and slide the main scale until the jaws contact the workpiece; read the value on the digital display. For internal measurements, use the internal jaws and expand them inside the bore until contact is achieved. For depth measurements, extend the depth rod and insert it into the feature to be measured. Use the fine adjustment and locking screw, if available, to obtain a stable reading.

Usage recommendations

Handle the caliper with care to avoid impacts and contamination of the measuring faces. Clean measuring surfaces with a lint-free cloth and, if necessary, a light application of suitable cleaning fluid that will not damage seals. Store the instrument in the roll case when not in use to preserve accuracy and the IP67 sealing. Replace the battery promptly when display dimming or error codes appear to maintain measurement reliability.
