Prior to cyclic corrosion testing, conventional salt spray (a continuous salt spray at 89.6˚F (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 cabinet, 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. Our CCT Cabinets can perform salt spray, Prohesion, and 100% humidity for most cyclic automotive tests.


Easy Programming and Sample Mounting

The CCT Cabinet 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 pre-programmed cycles.  The controller includes complete self-diagnostics, including warning messages, routine service reminders and safety shut down.


Precise Control of Fog Dispersion

The cyclic corrosion cabinet has a superior fog dispersion when 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 cabinet’s internal solution reservoir. The 120 liter reservoir has enough capacity for running most tests for 7 days or more. The reservoir has a built-in integral salt filter and alarm to alert the operator when the solution is low.


Fast Cycling

CCT 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.



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



◆ The cabinet structure is made of imported reinforced hard PVC plates with a smooth and flat surface,  aging resistant, corrosion proof, and easy to clean without leakage, avoiding color fading over time.

◆ Uses new TEMI 880 temperature and humidity controller, 7" HD true color LCD touch display.

◆ 1000 sections of programs; every section is capable of 999 circulating steps. The longest duration of every section is 99 hours and 59 minutes.

◆Function to link up to 10 sets of programs for a more complex test.

◆ USB interface to transmit data to a computer.

◆ Display real-time working graph.

◆ Temperature and humidity control with same channel coordination control method of P.I.D + S.S.R system.

◆ Heat and humidification are achieved through an internal boiler for fast heating. Temperature and humidity are evenly distributed

◆ Sealing of the chamber: the chamber cover and the chamber structure are water sealed to prevent leakage of water and salt spray.

◆ The spraying device is a tower (with adjustable height), able to guide the salt spray with fine granularity, the spray nozzle does not accumulate salt crystal.

◆ Lock open-type side cover plate to ease maintenance.

◆ Multiple safety protections: Oven temperature, water leaks, spray pressure.
