Easy, Fast and Efficient

The Recognoil® 3W is a handheld wireless analyzer: an oil substance fluorescence detector for mobile use with the option to connect to cloud storage. Compared to the previous two generations, the external design has been significantly redesigned by integrating the display, increasing the area under evaluation, allowing the connection of external probes, covering sensitive optical components, improving ergonomics and creating more than one grip for using the instrument.

Recognoil® technology uses the revolutionary principle of surface sensing of the fluorescence of oily substances, and thus represents a modern way of precise and repeatable inspection of surface cleanliness. It enables the visualization of pollution and thus the easy determination of its nature, at the same time as the possibility of detecting the slightest spot pollution. In industry, Recognoil® products have been used for more than 10 years, most commonly for checking the cleanliness of parts prior to coating or for evaluating the thickness and homogeneity of oil films in lubrication and preservation processes.

The new product thus combines the benefits of the most effective method of surface cleanliness control from TechTest s.r.o. with the requirements of Industry 4.0 and the comprehensive approach of Martin Tvarůžek Design.
