The BoreMaster Accurately Measures the I.D. of Tubing and Pipes and Tube Wall Thickness

Developed for the sport firearms and HVAC industries measuring tube I.D. on heat exchangers and shotgun bores is now easy and accurate. The BoreMaster is a totally unique product that accurately measures bore sizes 6" in depth into the tube or pipe and also tubing wall thickness. All readings are illustrated on the digital display in inches and metric. The measuring range is 0.375" to 1.250" diameter and includes a gage ring for calibration. The BoreMaster is spring loaded in the outward direction so the measuring process only requires insertion into the bore, releasing the probes and the internal diameter is displayed on the readout. The outward spring load eliminates the "human" factor when measuring assuring repeatable results. Included is a Delrin Wall Thickness clip that, when inserted onto the lower probe, allows the accurate measurement of tubing wall thickness. This is an accurate user friendly product that, within its range, supplies instant I.D. measurement 6" into any bore. Spring loaded probes always exert equal pressure on the bore, making readings accurate and repeatable • LCD resolution: 0.001"/0.1mm switchable inch/metric • Accuracy: +/- 0.001" • ID Measurement: Range – 0.375" to 1.200".
