DASQUA Professional Durable Steel Hardened Shock-Proof Dial Test Indicator With Calibration Certificate

The Dial Test Indicator (5221-1129) is a precision tool for detecting small surface deviations and measuring perpendicular displacement.It offers a measuring range of 0–8 mm (0–0.03″) with a high-resolution graduation of 0.01 mm / 0.0005″.Its hardened ground contact point and gear-driven mechanism deliver smooth and accurate readings.
Compact, robust, and durable with a satin chrome casing, it’s ideal for workshop and inspection tasks.

  • Measuring Range: 0–8 mm / 0–0.03″
  • Graduation: 0.01 mm / 0.0005″
  • Hardened Contact Point with Smooth Gear-Driven Movement
  • Robust Satin Chrome Casing & Protective Case

Description

The Dial Test Indicator (Item No. 5221-1129) is designed to measure minute deviations in surfaces perpendicular to the indicator axis, providing highly accurate readings for workshops, machining, and quality control. The balanced dial (0-10-0) or continuous dial (0-100) allows for reading differences from a reference surface or direct measurements, respectively. With a stylus length of 16.5 mm and 30 mm casing diameter, it is ideal for precise measurement in small or confined spaces.

Constructed with a robust frame and shock-proof gearing, the indicator combines durability and precision. The white dial edge enhances readability, and the gear-driven mechanism ensures smooth movement. Optional features include jeweled bearings, revolution counters, waterproof, dustproof, shockproof, and reverse reading for bore measurement. Electronic versions allow direct data transfer to computers for storage and analysis.

Features

  • With calibration certificate, tough shock-proof gearing,
  • A robust frame body for exceptional stiffness,
  • A white dial edge for easier reading, a ground contact point that has been hardened,
  • A satin chrome finish on the case for longevity,
  • and an accurate gear-driven design with a smooth movement.

Application

Dial test indicators resemble dial indicators very closely, however they have a measurement axis that is perpendicular to their axes. Dial and dial test indicators come in both analogue (mechanical dial) and electronic (digital display) varieties. Some electronic models electronically transport the data to a computer for storage and possible manipulation.
