Climatic test chamber Model 608

humiditytemperaturesalt spray

The ERICHSEN alternating climate corrosion tester model 608 for one (model 608-1) or two (model 608-2) freely selectable test chambers.

• Compact corrosion tester for cyclic tests and alternating climate stress or alternating corrosion stress. (See standards below).
• Connection for one or two test chambers made of environmentally friendly, acid- and heat-resistant PP material (can be combined in many ways – round or square test chamber).
• Integrated storage tank for approx. 200 l spray solution (guarantees refill-free test operation for up to one week).
• Integrated touch control panel for easy selection of test sequences and entry of test parameters.
• Cyclical corrosion tests such as alternating periods of salt spray, humidity, and drying tests can be started in a user-friendly manner and are then carried out fully automatically.
• Easy loading and unloading of the test chamber thanks to a pneumatically opening test chamber dome.
• Optimal setting of the solution to be sprayed can be preselected continuously.

Test chambers
Depending on requirements, different test chamber sizes with test chamber volumes of 400 l, 1000 l, or 2000 l can be selected. The test chambers (400 l or 1000 l) are available in round and rectangular designs. (For model 608-1: connection for one test chamber / For model 608-2: connection for two test chambers)

Purpose and application
Ferrous and non-ferrous metals are constantly exposed to the aggressive effects of moisture, acids, alkalis, gases, etc. Choosing the right surface protection is therefore crucial. The market offers many different materials and qualities, the properties of which cannot be determined by the (well-known) rule of thumb. That is why testing the suitability of corrosion-protected materials is the best protection against unpleasant surprises. Furthermore, comparative quality control during production is of course also becoming increasingly important. The best-known methods are spray mist tests with various sodium chloride solutions and exposure to condensation climates.

Principle of testing
In accordance with the standards and specifications listed below, aggressive solutions are atomized. These mists continuously or cyclically surround the samples placed in a heated test chamber. The corrosion resistance of the individual sample qualities is determined by the time difference between the first appearance of corrosion traces on the various samples.
