About Metal Cleanliness Testing – The CleanoSpector

The CleanoSpector is an easy-to-use handheld non-destructive cleanliness inspection instrument used for measuring organic contamination such as oil, grease and cleaning fluid on metal surfaces.  The instrument is widely used in Automotive and Aerospace industries and allows users to evaluate cleanliness directly at the cleaning process station, on the production line, during field work or in the laboratory.

The instrument has been specifically designed for monitoring cleanliness on manufactured metal parts during and after the cleaning process to ensure surfaces are free of contaminants before the next manufacturing process e.g. assembly, sealing, gluing, painting, printing, lacquering, laser welding etc.  The test results are measured in the degree of the cleanliness of  the metal parts in a percentage format or in RFU (relative fluorescence unit).

The measuring principle is simple – the CleanoSpector detects contamination due to its fluorescence which is excited by a UV light emitting diode (UV LED).  The fluorescence intensity depends on the amount of contamination found on the surface at the measuring point, i.e. the higher the fluorescence the more contamination found on the surface.

SITA CleanoSpector metal contamination testerAdvantages of Using the Fluorescence Method for Measuring Metal Cleanliness:

  • High product quality through controlled cleaning.
  • Easy evaluation of the cleaning results by comparing the cleanliness of part’s surfaces with a reference surface.
  • Detection of contamination on parts of various geometry.
  • Output of the cleanliness results in percentage (%) or RFU.
  • Easy and automatic calibration on a clean reference surface.
  • Variable parameter settings, e.g. quantity of measuring points for an optimal adoption on the inspection task.
  • Up to 255 parts’ profiles available.
  • Administrator & Operator Settings available

The CleanoSpector can also be integrated for automated inline inspection and robot mounted ideal for 3D part inspection.

Applications

SITA CleanoSpector metal contamination measurementApplication Fields:

  • Contact-free cleanliness inspection of part surfaces at push of button
  • Quality assurance of industrial cleaning processes
  • Layer thickness measurement e.g. of corrosion protection

Application Examples for Metal Cleanliness Inspection:

  • Cleanliness inspection of metal parts after machining
  • Inspection of functional surfaces after selective cleaning (laser cleaning, ultra-fine plasma cleaning, CO2 snow blasting, …)
  • Monitoring the cleanliness of metal parts before laser welding
  • Automotive crank shafts, pistons, cam shafts and con-rods after cleaning.
  • Pistons for hydraulic pumps before hardening – residual contamination has an influence on the steel quality in the hardening furnace
  • Stainless steel pipes before coating (vehicle construction)
  • Detecting residual agents and encapsulation material on bond pads before bonding
  • Surface inspection on electrical contacts after stripping of isolation material
  • Gear case parts before coating or bonding
  • Fluxing agent residues on gold bond pads on ceramic substrates
  • Medical device instruments and implants before delivering to the user
  • Cleanliness of parts before vacuum or powder coating
  • Controlling layer thickness of anti-corrosive agents, oils, waxes or bonding agents.
  • Cleanliness inspection of sealing groove in aluminium die cast housings for engine control units (ECU), automated driving control unit, power electronics for e-mobility, & pumps.
