Recognoil® is Czech technology that can detect even the slightest case of spot contamination. It utilizes the revolutionary principle of wide-area fluorescence imaging to detect greasy substances. Our portable Recognoil® 3W device scans the surface, then immediately displays and analyzes the results.

Our customers have been using products from the Recognoil® family for more than 10 years now. Most often they appreciate our products’ ability to help inspect parts for contamination before they undergo subsequent surface finishing processes, or the way they simplify evaluating the thickness and homogeneity of oil films in lubrication and preservation. Recognoil® 3W aids both technologists and managers alike, since it saves resources, lowers part rejection rates and enhances production process quality.

See your products through the eyes of Recognoil® 3W.


the optical probe

Start using Recognoil® 3W in your own facility. The scanning head of the detector can be fitted with a protective glass cover, so that the active surfaces of the detection head and surrounding optical elements are protected against contamination by undesirable substances and grease.

The device’s scanning head is made from a specialized aluminum alloy, which provides it with longer continuous operation in video mode, increases its detection power and ensures better heat dissipation for the UV emitters.



Analyze your surfaces from all possible angles, in every possible space. The device has a specialized multi-grip handle, fitted with two trigger-buttons. This way you can easily inspect products hooked onto a conveyor, acquire information above head level, or analyze the surface above an open space.

The design of the Recognoil® 3W device has been coordinated with leading Czech industrial designer Martin Tvarůžek, holder of multiple Red Dot Design Awards. Thanks to this cooperation, the device is highly ergonomic and fully thought-through – carefully considered down to the last detail.


A New Type
Of Analysis

Find out the state of contamination within seconds. Recognoil® 3W can evaluate an area as large as 27 x 20 mm. It is equipped with a white light, helping you to quickly identify the detection zone, and will document everything you need with no preparation required. Furthermore, the device can also read QR codes with settings and preferences, and evaluate other parameters, such as product surface wetting.

Recognoil® 3W enables you to monitor the quality of production with even greater scrutiny, thanks to a range of analytic methods for you to select. Besides performing inspections to ensure the high purity of various surfaces, it can also monitor surface tension.

Recognoil® 3W easily connects to external probes, which helps with processes like inspecting the inner surfaces of tubes, or similar areas that are difficult to access. Also, with Wi-Fi and Bluetooth, you can connect to other devices that monitor more than just contamination. When evaluating your acquired data, you might also appreciate its Cloud functionalities.
