Products for large-area surface scanning
Comparison of Recognoil ® 2W and QB outputs
The checked specimen:
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.

| Measuring a larger area The main advantage of Recognoil® is the ability to analyze and measure a larger part of the area, thus evaluating not only local pollution but also its distribution in the area.
It is also possible to select any smaller part of the scanned area and evaluate it separately.
|Contamination localization Thanks to the clear fluorescence map in 2D / 3D design, the Recognoil can be used to observe the occurrence of individual contaminants and automatically calculate the occurrence and total area in% by evaluating the image.|
| Objectivity Recognoil® wins here due to independence from the operator's judgment.
According to the preset limit, the Recognoil device directly reports only the result of the type "satisfies" and "does not comply" with the entered parameters.
|Reproducibility of results With the exception of the physical principle of fluorescence when multiple exposure of the same part of the surface to UV radiation, the output values of Recognoil products deviate in the interval of max. +/- 5 %.|

generation Before starting the measurement of a set of samples, it is possible in the Recognoil software to create a project to which individual measurements will be assigned and then exported in summary in PDF format.
| Low maintenance costs We recommend having Recognoil® devices cleaned and calibrated by our company once every 12 months.
However, these costs are still acceptable compared to other (special laboratory) methods.

|Suitable for robotics For the needs of inspection of parts using a robotic arm, we have developed a device of very small dimensions, which allows full evaluation of the surface condition as a hand-held detector Recognoil®2W.|
| Customer tailored We are also able to offer solutions that allow their use in specific conditions or applications.
We can also customize the SW according to your requirements (eg simple interface for operators, specific functions associated with image detection and UI, implementation in corporate networks, etc.).
| Interior surfaces Recognoil® products are manufactured using the 3D printing method, thanks to which we are able to offer products that are shaped suitable for use on the internal surfaces of components or technological units.
For example, we are able to offer equipment for inspecting the inner surfaces of pipes with a diameter> 45 mm.
| Long service life Recognoil® first generation devices have been used in production processes since 2011.

We will be glad to help you find out.
Does your production suffer from local contamination of the surface with oil and grease? Not sure if your parts are clean enough before surface treatment? Are you considering checking the effectiveness of degreasing? Is the cleanliness of components essential for you? Are the existing methods for you ineffective and insufficiently accurate? Do you want to be sure that adjusting or even changing the way parts are cleaned is really necessary or correct? Not sure if your lubricant application system is working properly? Want to know how much oil is applied to the surface of a part and whether the layer is uniform?
As the range of applications for Recognoil ® products is relatively wide, we meet the diverse requirements of our customers. Often the individual applications vary very widely and it is necessary to consult the suitability of individual products.
In addition, we are often able to offer individual tailor-made solutions, eg for detecting the inner surfaces of pipes and other hard-to-reach areas.
We will be glad to consult your request thoroughly with you first and test the suitability of our products on your parts.

Is the detection of oils, grease and other substances on the surface of the parts essential to maintaining the high quality of your production?
Do you care about good customer relations? Are you looking for an efficient and affordable solution for effective part cleanliness control?
Instrumental measurement of the cleanliness of product surfaces and monitoring of the application of oils and lubricants has been our task for more than 10 years, so we will appreciate if you contact us.
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.
