Insize Digital Hook Caliper 0.16-12" / 4-300mm Range Series 1122-300

Insize Digital Hook Caliper 1122-300

The Insize 1122-300 digital hook caliper is a precision tool designed specifically for accurate internal measurements in demanding applications. With a measuring range of 0.16–12" (4–300mm), it is ideal for checking groove widths and spacing inside bores or other hard-to-reach internal features. The hook-style jaws allow for measurements that standard calipers can't reach, making it an essential tool for machinists, inspectors, and quality control professionals.

Constructed from high-grade stainless steel, the caliper offers long-term durability and consistent accuracy. The digital display provides high-resolution readings in both metric and imperial units, and the intuitive controls include on/off, zero, mm/inch conversion, and a preset (+/-) function. An automatic power-off feature helps preserve battery life, while the movement-activated wake-up ensures it's ready when you need it. The 1122-300 also supports SPC data output via optional cables, allowing easy integration into digital inspection workflows.
