BANDOL WHEEL® Model 532/I & 532/II

Accelerated Weathering Instrument.  A reliable accelerated weathering instrument in a compact design for acceleration of natural weathering. BANDOL WHEEL® 532/I – designed for dry weathering cycles, was developed for quick but natural weathering, similar to outdoor exposure. To complete the weathering cycle, a mask can be added in the equipment which permits the introduction of obscurity phases without switching off the light source. The samples get a nominal UV radiation level corresponding to about “2 suns”. This permits an important acceleration in weathering that, at the same time, still correlates with natural weathering.


Compact instruments to determine the resistance to exposure to sun light using a Xenon high pressure lamp (1500 W or 2500 W). Adjustable levels of irradiance, uniform illumination by special mirror system, exchangeable filters for variable UV fraction. Programmable flooding system for periodic wetting of specimens available.


Portable instrument to apply defined scratches through coatings on specimen panels used for corrosion tests. Compact construction for fatigue-free operation. Scratch tool with van Laar geometry. Defined adjustment of the depth of the scratch in increments of 25 microns

Scratch Pen 426

A practical instrument with tungsten carbide tip 0.5 mm in diameter. The instrument is used for standardised scratching of corrosion test samples.
