Tube Hole Gauges make it easy to accurately measure tube IDs and tube sheet holes found in vessels such as heat exchangers, chillers, and surface condensers. These are the fastest gauges to give accurate readings saving you time.
Simply insert the tube gauge in the tube or tube sheet hole and use the three point ball contact to obtain an accurate measurement. The Reversible Dial Plate offers metric on one side and inch/decimal on the other to suit your needs.
The standard measurement depth is 4” (101.6mm) or 8” (203.2mm) (see the table to the right) with additional extensions of 8” (203.2mm) available.
