Description

INSIZE 3521-60 Digital Tubular Inside Micrometer

Are you looking for a precision instrument designed for measuring large internal diameters ranging from 6″ to 60″ (approximately 150 mm to 1,500 mm)? The INSIZE 3521-60 Digital Tubular Inside Micrometer is built for industrial and metrology environments, this micrometer combines rugged construction, fine resolution, and a durable design to deliver highly accurate internal bore measurements. It’s ideal for gauging large pipes, cylinders, or bores where standard inside micrometers may not reach.

 

Key Features

  • Excellent Resolution: Displays measurements with a resolution of 0.00005″ (0.001 mm), enabling very fine internal dimension readings.
  • Wide Measurement Range: Covers a broad range from 6″ to 60″, making it versatile for very large internal bores.
  • High Accuracy Design: Accuracy is specified as [0.00005 × (3 + n + L/2)]″, where n = number of extension rods and L = maximum measuring length in inches.
  • Carbide Measuring Faces: The contact surfaces are made of carbide, improving durability and wear resistance for consistent, long-term measurement.
  • Rugged Extension Rods: Comes with extension rods whose diameter is 0.866″, allowing flexibility to adapt to different measurement lengths.
  • Water- & Dust-Resistant (IP65): The micrometer is rated IP65, protecting it from dust ingress and water spray, making it reliable in harsher shop-floor environments.
  • Setting Standards Included: Supplied with certified setting standards so you can calibrate the micrometer before use.
  • Optional Data Output: There is an optional data output cable for SPC/data-logging applications (not always included).
  • Automatic Power-Off: Helps conserve battery life by powering down the unit when not in use (per catalog behavior).
