KD-CHECK: Water-Based Suspendable Wet Developer for Penetrant Testing

Wuppertal, Germany, 07 April 2022

Probes for Wall Thickness Measurement

During recent years, the use of waterbased wet developers, both water-soluble and suspendable, has become established in many areas of serial testing of aluminium components.
The newly developed wet developer KD-CHECK WDD provides the advantage that water is used as a carrier medium and thus there is no exposure of the environment or inspectors to solvent vapours. With waterbased wet developers, no highly flammable air-solvent mixtures can form, even in the case of improper handling, which improves operational safety. In addition, KD-CHECK WDD does not require special labelling. When used in PT systems, it is also advantageous that you can omit the use of drying ovens in most cases after intermediate cleaning when operated with preheated immersion tanks. KARL DEUTSCH now offers the typetested, water-based suspendable wet developer (form c) KD-CHECK WDD, order no. 9923, according to DIN EN ISO 3452-1, for testing with fluorescent penetrants. Of course, we are happy to provide samples for our customers.



Since its foundation in 1949, the owner-managed company KARL DEUTSCH has been engaged in the development and manufacture of equipment for non-destructive material testing. Mobile testing devices, stationary testing systems, sensors and chemical crack detection media for the testing methods UT, MT and PT are manufactured in two plants in Wuppertal by 130 motivated employees. Another 20 employees in foreign offices and a worldwide dealer network support the export business, which accounts for more than 60% of the turnover. Characterized by continuous innovation and reliability of the products, the brands ECHOGRAPH, ECHOMETER, LEPTOSKOP, DEUTROFLUX, FLUXA, KD-CHECK and RMG are internationally known today.
