Insize 3224 Tubular Inside Micrometers
The Insize 3224 Tubular Inside Micrometer series is built for measuring exceptionally large internal diameters, using a 2" travel micrometer head paired with a full set of extension rods. Covering ranges from 40"-80" up to 40"-200" (and metric equivalents from 1000mm up to 4000mm), the series is designed for jobs where standard bore gauges and smaller tubular micrometers simply don't have the reach. Each unit features carbide measuring faces for long-lasting durability and comes supplied with setting standards, making it a dependable option for large-scale manufacturing, heavy equipment fabrication, and industrial inspection work involving oversized cylinders, tanks, and bored components. As the range increases, additional extension rods are supplied to reach the full measuring capacity of each model.
