Recognoil^®

In the case of Recognoil^® 2W, the shading of the environment is solved by means of an exchangeable adapter. It is supplied as standard for flat surfaces. In addition, the shape and size of the adapter ensures the correct distance between the scanned surface and the detector. Scanning of complex surfaces, chamfers, small radii and scanning of spatial objects is therefore performed using special adapters in the form of a negative of the scanned surface. We produce these adapters using the 3D printing method on the basis of documents supplied by the customer.

For example, a shaped adapter is necessary for the correct measurement of cylindrical surfaces.

The described limitations due to the shape and size of the object are eliminated when using the Recognoil^® QB device, where I scan the object completely contactless and shielding is achieved by placing the object on the measuring table in the dark space of the box.

Recognoil^® products from TechTest, s.r.o. were developed primarily for the detection of fatty substances on metallic materials. It can be used for all types of lubricants and oils, with a few exceptions. They are not suitable for silicone-based oils. In addition to the mentioned oils and lubricants, which can be easily detected by this principle, they exhibit fluorescence, for example: dust, paper, plastics, etc. These contaminants are thus also able to be detected by our products. Suitable base materials are mainly metals (they do not show fluorescence). The device can be used on plastics, glass, ceramics, etc. based on verification of the properties of the material (or its composition, surface treatment, etc.).

Unfortunately, the fluorescence method used in Recognoil^® products is not a universal method in the sense of unpacking - measuring. Before purchasing, we recommend that you properly discuss your required application with us and best test it on a real sample of your products.

In order to provide the customer with enough information about the suitability of our products, we often need to ask for the following information:

We will then design a specific product for the customer and offer to perform a free test of the suitability of Recognoil^® for the required application.

The essence of the detection principle is the induction of luminescence of contaminants, its capture and subsequent evaluation using the supplied software. The standard output is the so-called fluorescence intensity [F.U. - fluorescence units] resp. its mean value related to the measured area and image output - fluorescence map showing the distribution of impurities on the surface of the part.

Yes. Conversion of the detector output to the surface concentration of the oil layer [mg.m^-2] or the film thickness [nm] is possible thanks to the software function, but it requires the import of a physical-mathematical model of oil made by laboratory sampling calibration.

Yes, both offered products Recognoil^® 2W and Recognoil^® QB are equipped with a set of LEDs and sound signaling allowing separate measurements without the need to connect to a PC or tablet with the possibility of determining the permissibility of surface contamination according to a preset limit. The pictograms on the LED panel are used for visual orientation of the operator. The operator can have 3 limits loaded in the device (for various surfaces, technological steps, etc.), which he can activate using the multifunction button of the device trigger. In addition, all exposures are stored in the device's memory - the operator has the option to download full-fledged images, make reports, etc. It is also possible to ensure the sending of measured data to the internal network or other specific functions according to individual customer requirements.

No. Recognoil^® products do not allow to determine the value of surface tension in mN.m^-1 from the principle of the method of detection of greasy pollution. However, it is possible under suitable conditions to determine in the laboratory the value of the surface tension corresponding to the value of the output of our devices, ie the fluorescence intensity.

For specific applications, it is not possible to set in advance a surface contamination limit value [F.U.] suitable for the intended application. The determination should be based on validation tests. On the contrary, it is very easy to determine the value of F.U. for perfectly degreased metal surfaces (this should always be as low as possible and ideally the same over the entire surface).

Yes, it must be taken into account that different types of oils show different fluorescence (due to their nature, additives, etc.). It is therefore not possible, for example, in the case of values of 10,000 F.U. one oil and 100,000 F.U. the other without laboratory calibration to talk about different layer thicknesses or surface concentrations. Due to the nature of the detection method, these values must always be determined using a mathematical model of the oil on the basis of laboratory calibration. The graph below shows an example of the behavior of individual oils in terms of fluorescence intensity depending on their nature and film thickness.

When working with the Recognoil^® according to the instructions in the user manual, there is no risk associated with exposure to UV radiation.

Recognoil^® devices are equipped with 2-level protection of the operator against unwanted exposure to UV radiation. The Recognoil^® 2W device checks the shading of the detector - ie whether it is attached to the object. At the same time, it is only used in combination with suitable measuring adapters to ensure complete shielding of UV radiation. Furthermore, the box is equipped with a magnetic sensor closing the working space. At the same time, during the exposure, the operator is separated from the radiation source by the walls of the box.

Recognoil^® instruments come with a factory calibration protocol. Reproducible results over a long period of time should be ensured if the device is stored and maintained properly. To verify the condition of the device itself, it is possible to order purity standards and calibration samples. To ensure stable and reproducible results, we recommend that you send the device at least once a year for regular maintenance (cleaning of optical elements, restoration of anti-fluorescent coating) and control calibration (output calibration protocol is included).

The basic benefits of Recognoil^® products can be summarized in the following points:

In addition, the acquisition of Recognoil^® can be considered a meaningful investment with a high return:

Yes, in some cases we are able to offer a completely unique device for the detection of contaminants according to the specific requirements of the client. For example, detection of greasy impurities on the inner walls of pipes, or devices for searching for dactyloscopic traces.

We also have experience with fully automated measurement or with the production of hand-held devices or single-purpose devices for operators.

We also offer customization of the supplied software according to customer requirements QR code, etc.).

Yes. The company TechTest, s.r.o. offers laboratory testing of your products Recognoil^® products

We also provide consulting services in the field of surface treatment and field measurement.

We also create measuring adapters and customized products for customers for in order to streamline and refine the parts inspection process.

Objectively evaluate changes in technological parameters, quality of production, suitability of some technologies, production operations, condition of process fluids and media during their life cycle and a number of other parameters related to the processes of cleaning, degreasing or application of oil films. from Recognoil^® products to production allows you to control inputs, processes and their outputs. This makes it possible to significantly reduce the scrap rate of production, increase its economy, reduce the environmental impact and streamline the entire production process.

We believe that Recognoil^® products are here for those who have customers and quality. On first place!

Verification test of the suitability of Recognoil^® products, when the customer sends about 3-5 parts for testing, we perform them free of charge. We will then send a report on the results obtained during the measurement and recommendations regarding the possible application of the device (eg the need to use special adapters or fixtures due to the shape of the object, etc.). use. We will verify whether the shape, material or type of contaminant is suitable for our detection method.

When packaging samples, it is primarily a matter of preventing contamination of the surface with the packaging material.

It is best to wrap the test sample in a foil and to prevent contact of the product surface with this foil by means of spacers. You can also use suitable plastic or metal boxes or other products to ensure that the inspected sample area does not touch the package or other inspected part.

Don't pack samples in paper towels! Don't use other textiles. The fibers of these materials are detectable with Recognoil^® products and would therefore affect the evaluation of the surface condition.

The better you pack your samples, the more objective the results we will achieve.
