• About this item.
• Accurate Measurements: Has an accuracy of ±0.003"; perfect measuring tool for household/DIY measurements 3 Measuring Capabilities:These digital calipers can be used to measure inside and outside dimensions and depths utilizing 1 pair of jaws and a depth rod Knurled Lock: Dial calipers feature a knurled lock screw that holds the sliding jaw in position when needed; a thumb-operated fine adjustment roller allows for one-handed use Colored Graduations: The extra large black dial features a red hand which completes 0.1 inch per revolution with 0.001" graduations in white ; the beam is engraved every 0.10" and 1" increment A covered rack helps prevent dirt and debriss from entering the rack and pinion movement.

Style:24" 0.001" 52-008-024-0 24" Maximum Measuring, 0.001" Graduation Interval Dial, Face Color Black The Fowler Extended Range 24" stainless steel dial caliper has dial graduations of 0.001" with +/- 0.003" accuracy, has a sliding jaw with lock, and a covered rack. The knurled lock screw holds the sliding jaw in position when needed. A covered rack prevents dirt and debris from entering the gearing, and helps prevent measurement errors. A thumb-operated fine adjustment roller allows for one-handed use. This caliper is used for measuring inside dimensions (ID), outside dimensions (OD), and depths. The caliper measures 0.10" per revolution of the dial. The black dial has 0.001" graduations in white and the beam is engraved every 0.10" graduation. The hardened stainless steel components, including the beam, measuring surfaces, rack, gears, and depth rod, offer corrosion resistance, increased accuracy, and long life. Self-contained movement eliminates gear misalignment, while the dual shock-proof drive mechanism reduces wear on the rack and pinion. An adjustable dial enables zero setting. Spring loaded anti-backlash gearing offers increased accuracy over standard gear configurations. The hardened stainless steel beam is polished to a satin chrome finish, to help prevent glare. This caliper comes with a fitted case. Dial calipers are measuring instruments commonly used for inspection in manufacturing to provide the precise measurements of an object. A pair of jaws attached to a long beam with a marked scale is used to measure inside, outside, and step measurements in standard or metric units. An additional depth probe slides along the beam to take depth measurements. One jaw is fixed to the end of the scale, while the other jaw slides along it to take measurements. A circular dial indicator is fixed to the movable jaw on a toothed gear rack that transfers movement of the jaws to the dial needle. The base measurement is taken from the long beam, which provides the initial whole measurement in inches or centimeters, and added to the dial reading, which provides fractional measurements in inches or millimeters. Compared to digital calipers, dial calipers are more durable, but are more susceptible to shock damage and prone to getting dirt in the gears, which can cause accuracy problems. Vernier calipers are more durable than dial calipers because they do not have internal moving parts, but they can be more difficult to read. Dial calipers are commonly used in fields such as metalworking, mechanical engineering, machining, and carpentry.
