Spi Tz 2/30 Dial Depth Gauge

Product Description

The SPI TZ 2/30 is a dial depth gauge used to measure the depth of holes, slots, recesses, and steps on workpieces. It provides direct-reading depth measurements via a calibrated dial face, allowing technicians to quickly verify dimensions without calculation. The gauge is a hand tool designed for use in fabrication, maintenance, and inspection settings where accurate depth measurement is required. At 0.98 pounds, it is lightweight enough for bench or field use. Trade professionals including machinists, pipefitters, and maintenance technicians rely on this type of instrument for quality control and layout work.

The TZ 2/30 is suited for industrial and commercial applications where precise depth measurement is part of standard workflow. Typical use cases include measuring counterbore depth, checking groove dimensions, and verifying recess depth on machined components. It is appropriate for shop floor inspection, maintenance shops, and light fabrication environments. The dial readout format makes it accessible for technicians who need repeatable measurements without electronic instrumentation.

Installation Notes

Dial depth gauges require no installation but should be handled and stored carefully to maintain calibration accuracy. Zero the gauge on a known flat reference surface before taking measurements. Protect the dial mechanism and probe tip from impact and debris. Calibration should be verified periodically against a certified gauge block or reference standard per applicable quality procedures.
