Salt Spray Prohesion Test Chamber
Cyclic corrosion testing provides the best possible laboratory
simulation of natural atmospheric corrosion.
Research indicates that test results are similar to outdoors in
resulting structure, morphology, and relative corrosion rates.
Cyclic corrosion chambers from BOTO GROUP can run traditional salt
spray, Prohesion, and most cyclic automotive tests.
Chambers are available in different sizes to fulfill a wide range
of testing requirements.
Cyclic corrosion testers are the simplest, most reliable, and
easiest to use corrosion testers available.
Overview Cyclic Corrosion Testing
Prior to cyclic corrosion testing, conventional salt spray (a
continuous salt spray at 35˚C), was the standard way to simulate
corrosion in a lab. Because conventional salt spray methods failed
to mimic the natural wet/dry cycles of the outdoors, test results
frequently provided poor correlation to outdoors.
In a cyclic corrosion tester, specimens are exposed to a series of
different environments in a repetitive cycle that mimics the
outdoors. Simple cycles, such as Prohesion, may consist of cycling
between salt fog and dry conditions.
More sophisticated automotive methods may call for multi-step
cycles that incorporate humidity or condensation, along with salt
spray and dry-off. Within one chamber, it is possible to cycle
through a series of the most significant corrosion environments.
Even extremely complex test cycles can easily be programmed with
the controller.
Precise Control of Fog Dispersion The cyclic corrosion chamber has superior fog dispersion compared
to conventional systems, which cannot vary volume and distance
independently. A variable speed peristaltic pump controls the
amount of corrosive solution delivered to the spray atomizer, while
the air pressure regulator controls the distance of the
“throw.”Note that purified water is required for proper operation
of corrosion testers.
Internal Solution Reservoir Space utilization is maximized and maintenance is minimized with
the tester's internal solution reservoir. The 120 liter reservoir
has enough capacity for running most tests for 7 days or more. The
reservoir has an integral salt filter and a built-in alarm to alert
the operator when the solution is low.
Fast Cycling Testers can change temperatures exceptionally fast because of
their unique internal chamber heater and their high volume
cooling/dry-off blower. An additional air heater allows very low
humidity dry-off exposures. Conventional chambers with water
jackets cannot cycle rapidly because of the thermal mass of the
water, nor can they produce low humidity.
Affordable Cyclic corrosion testers offer state of the art corrosion testing
technology, reliability, ease of operation and easy maintenance –
all at a remarkably affordable price.
Other Accessories
BOTO offers a fog collection kit for the tester, which consists of a
set of six graduated cylinders, o-rings, and collection funnels.
Also available is a one-year maintenance parts kit, which consists
of eight pump tubes, one air filter, two solution filters elements,
and a handy hex wrench.
Salt corrosion spray test chamber Configured for your specific tests Grande makes rain and spray
testing easier by offering a standard chamber capable of published
and OEM proprietary test methods. The standardized design can be
configured for the rain/spray tests you need, eliminating the
guesswork in buying a chamber. The system is based on the
specification requirements, and can also accomplish individual
automaker’s tests, as well as electrical-enclosure tests. Our
Design BOTO's modular design allows you to add on additional
features, depending on the number and type of tests required. One
possible choice is to integrate the spray system with a regular
temperature and humidity chamber to save money and floor space,
while also creating an opportunity to simulate actual operating
conditions your product may experience. Our system uses multiple
control solenoids to vary the water's spray volume/pressure. A
holding tank prepares the water to the desired temperature, if
required. A pump ensures the water is delivered in the proper
pressure range. The water is fed to a motorized manifold that
rotates the spray arms. Each spray arm has an adjustable valve to
allow finer control of the spray.
