UV Box Model 636

Accelerated weathering tester, UV aging test (UV radiation), moisture condensation.  UV radiation is responsible for almost all the processes of photo degradation of durable materials exposed to the external environment. The fluorescent lamps used in the UV-BOX 636 simulate critical UV short waves and realistically reproduce the damage caused by sunlight. The types of damage that can be simulated with the UV-BOX are the following: color change, loss of gloss, chalking, cracking, cracks, blistering, veiling, brittleness, loss of strength and oxidation. Dew is mainly responsible for most of the moisture that occurs during outdoor exposure, much more than rain. The condensation system of the UV-BOX 636 realistically simulates dew and amplifies its effect through the use of high temperatures.  The condensation process automatically purifies the network water used in the system. This is because the process of evaporation and condensation of water on samples is actually a distillation process, which allows to remove all impurities.  UV-BOX can accommodate up to 48 standard samples (75 mm x 150 mm)¸it is possible to create special sample holders according to customer specifications. The operation is done via a modern touch screen panel.  The UV lamps are not included in the delivery.

The accelerated UV aging test reproduces the damage caused by sunlight, rain and dew. In a few days or weeks of exposure of the samples inside the UV-BOX 636, damages occurring in months or years of outdoor exposure can be reproduced.  Simulate aging due to external atmospheric agents, UV-BOX subjects the materials to alternating cycles of UV radiation and humidity at controlled high temperatures. The instrument simulates the effects of sunlight through the use of special UV fluorescent lamps and the simulation of the effect of dew and rain occurs through condensation or a spray of water (Spray option).

BANDOL WHEEL® Model 532/II

Accelerated Weathering Instrument BANDOL WHEEL®H 532/II Photo-ageing instrument for acceleration of natural weathering
for “wet or dry” cycles. 
Accelerated Weathering Instrument.  A reliable accelerated weathering instrument in a compact design for acceleration of natural weathering. BANDOL WHEEL® 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.

SOLARBOX 522

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.

SCRATCHMARKER 427

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.
