Q-FOG Cyclic Corrosion Testers


Product Description

View Product Brochure

 

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.

Q-FOG cyclic corrosion chambers from Q-Lab can run traditional salt spray, Prohesion, and most cyclic automotive tests. Q-FOG chambers are available in two sizes to fulfill a wide range of testing requirements.

Q-FOG cyclic corrosion testers are the simplest, most reliable, and easiest to use corrosion testers available.

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 Q-FOG 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 Q-FOG 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 Q-FOG controller. See LF-8110 - Q-FOG Specifications or visit our standards page for a detailed list of test methods met by the Q-FOG chamber.

Q-FOG corrosion test chambers are available in two types. Model SSP performs traditional salt spray and Prohesion tests. Model CCT performs salt spray, Prohesion, and 100% humidity for most cyclic automotive tests.

Easy Programming and Sample Mounting

The Q-FOG test chamber is designed to cycle between four conditions: Fog, Dry-Off, 100% Humidity (Model CCT only), and Dwell.  Test conditions, time, and temperature are controlled by a built-in microprocessor.  A remarkably simple user interface allows for easy user programming and operation.  The operator can quickly create new cycles, or run any of the programmed cycles.  The Q-FOG controller includes complete self-diagnostics, including warning messages, routine service reminders and safety shut down.

The Q-FOG tester has a low belt line and an easy opening lid for easy sample mounting.  The SSP-600 and CCT-600 models have a capacity of about 160 test panels of 75mm x 150mm in size.  The SSP-1100 and CCT-1100 models have a capacity of 240 test panels.

Precise Control of Fog Dispersion

The Q-FOG 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 Q-FOG corrosion testers.

Internal Solution Reservoir

Space utilization is maximized and maintenance is minimized with the Q-FOG 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

Q-FOG 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

Q-FOG cyclic corrosion testers offer state of the art corrosion testing technology, reliability, ease of operation and easy maintenance – all at a remarkably affordable price.
