Hole Gauge

The TECO hole gauge

Is a unique and simple instrument that quickly and accurate measures, with a three point contact, the inside diameter of tube and tube sheet holes.

The reversible dial plate allows the user to measure in both inch/decimals and metric.

Our standard adjustable depth is 4” (101.6 mm) or 8” (203 mm) dependent on the model.

All gauges are furnished with setting ring and packed in a wooden carrying case.
