Salt spray test chamber Model 606

Purpose and application
Ferrous and non-ferrous metals are attacked continuously by humidity, acids, solutions, gases etc. It is therefore vitally important to choose the correct surface protection. There are many materials and qualities on the market and their properties must be properly assessed. Materials intended to prevent corrosion must be tested if failures are to be avoided. Furthermore the comparative quality control during production is of increasing importance. The best known processes employ spray vapour tests using various salt solutions as well as condensation water climates.

Test principle
Aggressive solutions are turned into a vapour mist in accordance with the tests that are listed below. These vapours surround the specimens in the test chamber either continuously or in a cyclic manner. The corrosion resistance of the individual specimens is established on the basis of the difference in time before the first corrosive effects become apparent.

Design
The ERICHSEN Corrosion Testing Instrument, Model 606, 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.
Our corrosion testing instruments can be compiled individually by the user.
For this purpose, two control cabinets are available, either for the equipment with one test chamber (Model 606-1) or as double chamber device (Model 606-2).
Various test chamber sizes with test volume of 400 l, 1000 l or 2000 l can be selected regarding the requirements. The test chambers (400 l and 1000 l) are available in circular and rectangular design. The circular design provides even distribution of the salt solution vapour over the entire test zone. When tests are required on larger working parts, it is often not possible to employ a test chamber of circular symmetry. For this reason, as an alternative, rectangular test chambers with a capacity of up to 2000 l (special dimensions upon request) can be supplied.
The scope of supply includes 3 specimen holder for weathering panels (per test chamber), with test capabilities of 18 test panels per specimen holder. 
The control cabinet 606-1 is equipped with a JUMO DICON touch for easy operation and monitoring of the test equipment as well as the necessary regulating and control instruments for monitoring the chamber temperature, the temperature of the humidifier, the spray pressure and the duration of the test.
The scope of supply includes an equipment for tests in heat damp atmospheres according to DIN EN ISO 6270-2 (CH) as well as two condensate receptacles.
The top of the test chamber dome is pneumatically opened and closed so that both hands can be used to lodge the specimens. A dosing pump serves for an infinitely variable adjustment to achieve optimum consumption of spray solution. The large storage tank for approx. 200 l salt solution allows continuous testing without attention over a period of up to a week. A circulation pump for mixing the salt solution in the storage tank is permanently installed in the lower part of the control unit.
Constructed similarly to the control cabinet 606-1, the control cabinet 606-2 (for connection of two test chambers) is equipped with two dosing pumps and two circulation pumps. There are two integrated storage reservoirs for spraying liquid (each 150 l). The package includes four condensate receptacles.
