Corrosion Testing Apparatus
The ERICHSEN Corrosion Testing Instrument, Model 608 Basic, takes full advantage of our wide experience in the construction of all kinds of testing equipment as well as of the information and worldwide feedback received from users. Made of impact resistant, eco-friendly polypropylene material each instrument forms a closed unit. The Corrosion Test Apparatus, Model 608-Basic, consists of a test chamber of 400/1000/2000 l capacity, and a built-in control unit as well as an external storage tank for the spray solution. The external storage tank for approx. 200 l salt solution allows continuous testing without attention over a period of up to a week. A dosing pump serves for an infinitely variable adjustment to achieve optimum consumption of spray solution. A circulation pump for mixing the salt solution in the storage tank is permanently installed in the lower part of the control unit. hecontrol cabinet 608 Basic is equipped with a PLC (programme logic control) SIEMENS D7 200.The test cycles as well as the test parameters are entered using the SIMATIC touch screen. Cyclic corrosion tests executed e.g. in accordance with the specification of VDA, VW or SWAAT, can be started in a user-friendly manner. By default, five programs for standard test sequences are provided. Program number 6 is available for customized programming.However, programs 1 to 5 can also be customized by the user to meet their specifications. After placing the specimens and the condensation receptacles in the test chamber, the test takes place fully automatically. The top of the test chamber dome is pneumatically opened and closed so that both hands can be used to lodge the specimens.
