ERICHSEN Humidity Cabinet CORROTHERM 610/610e
In accordance with the most required standards
(DIN, DIN EN ISO, ISO, ASTM, BS, JIS, IEC, MILSTD)
Purpose and application
Ferrous and non-ferrous metals are attacked continuously by humidity, acids, solutions, gases etc.. Thereforethese materials require the necessary preparatory techniques and protective coatings. Over and above this, the increase in preparatory treatment demands and environment protection aspects lead to further system improvements of coating substances. The choice of the correct combination of material and the surface protection is therefore of decisive importance for the corrosion resistance of work pieces and assemblies. Corrosion tests are therefore still very essential for quick quality control and for the investigation of weak areas. In order to make these tests comparable, national and international standards have been drawn up for test conditions and duration.
The CORROTHERM 610 is an extremely compact, space-saving corrosion test apparatus, made entirely of non-polluting PP material and contains all the necessary equipment for testing in accordance with the most frequently used spray mist and condensation water tests (DIN 50 021, DIN EN ISO 6270-2, DIN EN ISO 7253, ISO 11503, ASTM B 117, ASTM B 368 T “CASS TEST”).
Two different capacities (400 l and 1000 l) and two different versions (610 and 610e) are available.
The box-type construction with the front door makes provision for ease of control and accessibility to the test chamber. The spray nozzle is fitted into the inner rear panel so that the entire test chamber is available for the specimens. Suspension rods are fitted across the test chamber at three different levels and on these smaller ssemblies, directly or test panels can be placed on “U” shaped holders. In the bottom of the test chamber is a heating element to provide optimum conditions for humidifying and temperature control in the test chamber. Within the test chamber itself is the storage tank for up to 100 litres (400 l Version) or up to 280 litres (1000 l Version) of spray solution. This enables the test apparatus to work over the weekend without supervision. The Corrosion Test Apparatus of the CORROTHERM 610 series is manually operated. Clearly arranged buttons are available for functions such as the salt spray test, condensation water test and vapour evacuation. Via the control buttons, which are at eye level, the temperature display, time switch, and the test duration display functions are available and also permits the automatic switch off function on completing the pre-programmed test time (i.e. 240 h). The display is reversible and can represent the test time in hours and minutes. With an adjustable valve, also at eye level, the spray pressure can be finely adjusted and can be read from the manometer directly above. A continuous controllable dosing pump (low-maintenance diaphragm pump) ensures the correct quantity of spray solution to the nozzle and the humidifier works automatically.
The CORROTHEM 610e has the same capacity as Model 610, but is operated with a microcontroller and a four-lined LCD whereby all important parameters can be called up and entered. The display shows, amongst other things, the chamber temperature, the humidifier temperature and the spray pressure. As well as the pre-programmed test cycles (from the manufacturer) a total of up to 15 programmes can be stored.
Optionally, via an interface, the data can be transferred to a built-in printer.
