Cat # IRG-3600

Measures the inside radius and diameter for cylindrical objects. Diameter measurement is calculated by doubling the radius measurements. This is an essential tool for acquiring quick measurements for large pipes, metal rolling or fabrication and measuring large tanks.

Items comes with a Variable Arc, a durable device that when mounted on the IRG-3600 can form the arc of the radius you have set on the gauge. Perfect for creating scaled models, drafting buildings, arch way construction, millwork and more. Please see the User Guide Print-Ready PDF for more information.

Measuring Range: From 6 inches (150 mm) to 144 inches (3600 mm) with a tolerance of +/- 0.5%. Gauge can be sent with a Letter of Conformance, upon request, but cannot be calibrated. Standard (inch) and metric are on one gauge.
