Length

NSAI NML can calibrate the following instruments:

• Gauge blocks, length bar standards, step gauges, optical flats and parallels
• Pin gauges, plug gauges, ring gauges, taper gauges, gap gauges
• Glass scales, line scales and graticules
• Rulers and measuring tapes
• Angle gauges, electronic levels, spirit levels and inclinometers
• Micrometers, calipers, height gauges, dial gauges and dial test indicators.
  
  We can also offer a range of 2D and 3D measurements using tactile and/or optical probes,
  suitable for non-standard gauges or products produced by AM or SM methods.
  These measurements include roundness, squareness, parallelism etc.
  Also available are structural features such as porosity, density, volume

The above list is not exhaustive, and the laboratory can calibrate a wide range of length
standards and measuring instruments compatible with its measurement capability outlined below.
