Handheld test instrument for inspecting metal cleanliness

Dyne Testing, an Intertronics brand, offers the CleanoSpector, which supplies contact-free cleanliness inspection and aids in the quality assurance of industrial cleaning processes. The device is an easy-to-use, handheld, and non-destructive inspection instrument specifically developed for measuring the cleanliness of manufactured metal parts to ensure surfaces are free of contaminants before the next manufacturing stage.

The device measures organic contamination on metal surfaces, such as oil, grease, coolants, release agents, and cleaning fluid. It is widely used on production lines, during fieldwork, and in laboratories across industries, including automotive, medical device manufacturing, and aerospace.

The instrument provides non-contact and non-destructive inspection of metal surfaces at the push of a button. It detects contamination on the metal’s surface by emitting focused UV light onto the surface and measuring the fluorescence from any organic compounds. The results are displayed in the cleanliness degree of parts in per cent. The higher the measured fluorescence intensity, the more intense the contamination, and the lower the displayed cleanliness.

“The CleanoSpector is suitable for use in the laboratory as well as for use around the manufacturing process,” said Alison Fox, Dyne Testing brand manager. “The instrument can work on metals, ceramics, and glass. It has various spacers that can provide easy measurement of different part shapes to ensure optimal focal length.”

The technology of fluorescence measurement uses the device to allow reliable monitoring and recording of part cleanliness after cleaning. Also, as an initial check before cleaning, it can ensure that the degree of contamination of the parts remains within the permissible limits for which the cleaning process was specified and designed. Parameter deviations and cleaning system faults can be identified quickly, and process reliability can be greatly increased. A software option provides computer control of the device and the recording and management of cleanliness measurement data.
