Glass scales with graduation 0.1 mm for calibration of profile projectors or for the construction of custom-made products for length measurement

On backorder (Delivery time: 10 - 14 days after order)
The uniscale series of precision glass measuring rods have graduations and numbers consisting of vapour-coated hard chrome. One scale each in metric and inch increments. The smallest increment on the inch scale is 0.005". The minimum increments on the metric scale are 0.1 millimetre.

These uniscale glass measuring rods are identical with the rods in the chrome scale and micro-chrome scale series however without magnifier, handle, white cover strip, etc. These rods are suitable for installation in self-made mounts.

These valuable precision glass measuring rods are delivered in a stable wooden case to protect them from damage. Uniscale rods are available in lengths of 300, 500, 800, 1000, 1400, 1600 and 2000 millimetres. Special lengths available on request. These glass measuring rods have the advantage that their expansion is minimal when heated. Temperature variations therefore have hardly any effect when using uniscale rods.

Specification:

  • Upper measuring scale: Pitch = 0.005" labelled (small) 0 .05 .10 ... (inch) labelled (large) 0 1.0 2.0 ... (inch)
  • Lower measuring scale: Pitch = 0.1 mm labelled (small) 0 1 2 ... (mm) labelled (large) 0 10 20 ... (mm)
  • The graduations and numbers vapour-deposited on the glass body in hard chrome are razor-sharp and absolutely scratch-resistant.
  • The graduation mark thickness is 0.010 mm.
  • Accuracy of graduation according to DIN 864: ± (0.003 mm + 3L / 1'000'000)
  • Example: L = 500 mm, graduation error <= 0.0045 mm (The dimensions refer to 20°C)
  • Coefficient of thermal expansion: 9 x 10-6 / °C. Refractive index = 1.5195
  • Material = Float glass (selected)
  • Scale not averaged / centred on glass body! Multiple use)
  • Length of glass body = nominal length in inches x 25.4 mm / inch + 49 mm
  • Width of glass body = 39 mm Thickness of glass body = 6 mm

Available in lengths (measuring range of the double scale):

  • 300 mm / 12" = total length 353.8 mm (± 1mm)
  • 500 mm / 20" = total length 557.0 mm (± 1mm)
  • 800 mm / 32" = total length 861.8 mm (± 1mm)
  • 1,000 mm / 40" = total length 1,065.0 mm (± 1mm)
  • 1,400 mm / 56" = total length 1,471.4 mm (± 1mm)
  • 1,600 mm / 64" = total length 1,674.6 mm (± 1mm)
  • 2,000 mm / 80" = total length 2,081.0 mm (± 1mm)
