Recognoil® products allow you to visualize, measure, and document what is not visible to the naked eye.


Within seconds, contactless and without any need to prepare the surface of the part, visualize and quantify the presence of surface contaminants.


Thanks to this, you have the opportunity to really assess the suitability of the surface for other technological operations.


Find out if the object is really clean




The cleanliness of the surface, ie the presence of grease, corrosion products (oxides), dust particles and other contaminants, plays an important role not only in surface treatments, but also in the joining (welding and adhesive bonding) of material.

In the case of surface treatment, greasy surface contamination affects the adhesion and appearance of the coating. In soldering and welding, grease is undesirable mainly due to the quality of the joint and the occurrence of possible defects. In the case of gluing, again, a very clean surface condition is required to achieve sufficient adhesion of adhesive (glue).

Measurement with Recognoil® oil layer detector is a modern alternative to surface energy measurement equipment (pens or inks) and contact angle meters. The results correlate directly with the substrate cleanliness and it is possible to convert them to values of layer thickness, surface oil concentration or surface energy.

With Recognoil® cleanliness analyzers, the detection of greasy, oily and other surface contaminants can be completely non-contact. In addition to the main image output of the surface condition and primary unit of contamination (fluorescence intensity), the result of the measurement can also be the thickness of the oil film, the surface oil concentration or the value of the surface tension (surface wettability).

Contactless measurement of surface grease after degreasing and cleaning, allowing you to avoid undesired defects in coatings, reduction of paint or adhesive (glue) adhesion and eliminate the formation of pores in the weld joint. Very easily, you can also start the optimalization of cleaning processes, or verify the suitability of the degreaser and the overall degreasing technology.

We offer Recognoil® detectors not only as mobile hand-held devices for determining surface cleanliness, but also as products for installation in production lines or as laboratory and workshop units for operators. Degreasing control can thus be comprehensive and reliable throughout production.


Controlling the application of oil films is also possible and can have a major impact on the economy and environmental performance of processes where oil thickness during lubrication and preservation affects the life of tools and products. Measuring the oil film and its spreading on the surface (homogeneity) will help you in processes where it is important to apply the oil to the material correctly and evenly (pressing, drawing, preservation, etc.).

Products for large-area surface scanning


Recognoil® 2W


Recognoil ®2W is a handheld wireless analyzer - oil and grease fluorescence detector for mobile use. Together with a tabletPC and Recognoil ® PRO software, it forms a very efficient and productive system for fast random and systematic testing for the presence of residual greasy contamination in large and small plants. The measurement does not require any special surface preparation and the interpretation of the results is easy even for less qualified workers thanks to the OK / NOK operator mode.

The instrument is applied directly onto the analyzed surface.

Main output from Recognoil QB - contactless determination of surface cleanliness or oil film thickness

Recognoil ® products are primarily intended for checking the condition of the surface of metal objects.

Thanks to surface "large-area" scanning of the controlled area and visualization of fluorescence intensity values in the color spectrum of the fluorescence map, even the smallest contamination sources can be immediately located and thus verify the suitability of the surface for further operations.

The lower the measured value of the fluorescence intensity, the cleaner the surface.


Recognoil® PRO SW

All Recognoil® devices come with advanced PRO software, which not only is used to display scanned and evaluated areas, but also allows further data processing and includes a number of unique functions.

For example, Recognoil® PRO software allows automatic conversion of the fluorescence value to layer thicknesses [nm], resp. area concentration [mg.m-2] using a physical-mathematical model of oil made by laboratory sampling calibration.

We also offer customization of the supplied software according to customer requirements (data export to the database, automatic setting of limits for a given part, import of a measurement guide according to a QR code, operator modes, company protocols, etc.).

With Recognoil®, you can verify that your processes are actually working and that the surface of the parts meets the requirements for further processing. By introducing a control mechanism into production, you will prevent the occurrence of immediate and hidden defects of parts and increase the economy of production. Thanks to the visualization of the distribution and intensity of pollution, the assessment of the surface condition is simple and clear.

Functions included in Recognoil® SW PRO:

  • display image data and measurement results
  • selection of areas of measured areas
  • naming the measurement (sample)
  • sorting and searching files
  • export files (pdf, jpg, txt)
  • creation of protocols (photo documentation of parts, image and text notes)
  • setting metering parameters (exposure type, image quality, etc.)
  • conversion of fluorescence units to oil thickness or area concentration

FAQ

What type of contamination is present on the surface of the industrial parts?

In case of metal substrates - grease, oil, oxide layers, dust, chlorides, inks, chalks, adhesive (glue) residues, metal chips and other solid particles are most often present on the surface. Recognoil® can detect these and other contaminants on the metal surface.

How common is greasy surface?

A thin greasy film is very common on the surface of parts during their production. Its source are mainly fatty substances - oils, lubricants, preservatives, silicones, etc., which are, at a certain stage of production intentionally applied to the surface (lubrication, cooling, preservation, masking) and in another step relatively difficultly removed by degreasing. Importantly, grease contamination of the surface does not only affect metals, but also plastics and other materials.

Where does it make sense to measure the thickness of oil film on the surface?

The thin oil film most often has a lubricating and protective (protection against corrosion and wear) function on the surface of the object. A great example can be stamping, pressing or deep drawing, where the oil reduces friction and thus tool wear. Controlled uniform application of lubricant of the correct thickness has a positive effect on the overall course of the forming process and reduces the scrap rate of production.

We use dyne pens and test inks to determine grease, what makes Recognoil® different?

Unlike the methods based on the principle of surface wetting, ie the determination of surface energy, the detection of undesired substances by means of Recognoil® products is performed by induction of luminescence of contaminants, its capture and subsequent evaluation using the supplied software. Detection of contamination on the surface of parts is thus significantly faster, more objective compared to test inks and pens and allows monitoring of surface cleanliness even in fully automated operations.

Does grease affect the adhesion of the adhesive (glue) to the surface?

Cleaning the surface before applying the adhesive is just as important as before applying the paint or other surface treatment. The wettability of the surface (the ability of the substance to adhere to the surface) is fundamentally affected by grease. Quality control of surface preparation process with the Recognoil® device in gluing and painting processes enables not only the evaluation of residual surface lubrication (ideal surface wettability), but also the presence of dust particles and other contaminants.
