The hand-held measuring device SITA CleanoSpector is used for Cleanliness inspection of parts to ensure product quality and follow-up processes such as adhesive bonding, coating, welding, hardening and bonding.
Unwanted Filmic contamination such as oils, greases, cooling lubricants and release agents are detected by measuring the Fluorescence intensity.
The easy to use SITA CleanoSpector is suitable for quality assurance directly in the manufacturing process.
Features
- Mobile and robust device for flexible use at the process and in the laboratory
- Intuitive operation: simple and fast measurement at the push of a button
- Device with easy to handle sensor head and display unit enables measurement of even small parts or complex geometries
- Check and adjustment with working standards

For 15 years, the SITA CleanoSpector is used successfully and worldwide in a wide range of applications and industries:
- Cleanliness inspection of metal parts after processing with production aids (monitoring, optimisation and control of cleaning processes)
- Inspection of functional surfaces after selective cleaning (laser cleaning, ultra-fine plasma cleaning, CO2 snow blasting, ...)
- Inspection for residues of release agents on aluminium die-cast parts before adhesive bonding
- Monitoring the cleanliness of gear parts before laser welding
- Inspection for filmic contamination on parts in medical or vacuum technology
- Detecting flux residues and contamination through sealing compound in electronics production
- Surface inspection on electrical contacts after stripping of isolation material
- Inspection for sufficient layer thickness when applying corrosion protection oils or when applying a primer

The measuring method uses the characteristic of organic substances to fluoresce. UV light is focused and radiated onto the surface. The contamination fluoresces. The intensity of the Fluorescence increases with the layer thickness of the contamination. The intensity is measured in RFU: Relative Fluorescence Unit.
The lower the measuring value in RFU, the cleaner the surface.
