The Z340 Semi-Automatic Bench Top Coating Analyser has been developed to give detailed distribution analysis of the internal and external lacquer on an aerosol can.


The system utilises state-of-the-art non-contact spectroscopy techniques and is suitable for both aluminium and steel aerosol can inspection.

Measurement Features

  • Internal Lacquer | Accuracy: +/- 0.2 µm | Capability: 0.4 µm
  • Over Varnish | Accuracy: +/- 0.2 µm | Capability: 0.4 µm


Technical Specification

  • Aerosol Can Materials | Aluminium/Steel
  • Outer Body Diameter | Typical Range: Ø 35 – Ø 66 (but limited to)
  • Can Height | Typical Range:  60.00 – 230.00


Gauge Features

  • Internal Lacquer Thickness / Weight
  • External Varnish Thickness / Weight / OV (Over Ink)
  • Dual system equipped with two spectrometers – Visible Light and Near Infrared (NIR) light, enables the OV/over ink inspection
  • Brand-new fibre set up creating a smaller spot size to optimise measurement of rim coat and reverse wall, both with dedicated tooling to enable precise location of measurement positions on both features
  • Enables monitoring and control of the lacquer distribution
  • Absolute, not inferred, lacquer thickness measurement
  • Multi-size capability so no need for change tooling
  • Traceable measurements to NIST standards
