Corrosive gas test chamber tests gases H2S, SO2, Cl2 with carrier gas N2 (nitrogen), NO2, with carrier gas synthetic air and many other test gases. It has wide range of applications in industries including automotive, aviation and space, plastics, building materials, clothing, chemicals and manufacturers of sports articles.

It is used for various purposes to simulate the conditions that a manufacturer or supplier product will be exposed to in actual service conditions. This equipment allows selective and reproducible accelerated corrosion testing complying with the requirements of relevant national and international standards. By using these tests the user is able to make statements regarding the corrosion resistance of his products, or to take corrosion-inhibiting measures.

Corrosive gas test chamber has a Controller board with removable Colour Touch Panel. There are ASTM standards relating different variations of creating and controlling fog and humidity in cabinets for corrosion testing of a broad spectrum of products, from decorative electrodeposited coatings to the evaluation of the corrosives of solder fluxes for copper tubing systems.

The basic humidity test is most commonly used to evaluate the corrosives of materials or the effects of residual contaminants. Cyclic humidity tests are conducted to simulate exposure to high humidity and heat typical of tropical environments. The cabinet performing such tests should be equipped with a solid-state humidity sensor reading the current humidity condition and a feedback controller. The mechanism used to control the humidity moves chamber air via a blower motor and passes it over a heater coil in the bottom of the chamber with an atomizer nozzle fogging into this air stream.

Controlled amounts of corrosive gases are added to humidity to replicate more severe environments. Some of these tests are designed to reveal and amplify certain characteristics of a material. The moist sulphur dioxide test is intended to produce corrosion in a form resembling that in industrial environments. A very sophisticated variation of these tests is the flowing of mixed gas test that consists in introducing parts per billion levels of pollutants such as chlorine, hydrogen sulphide and nitrogen dioxide in a chamber at controlled temperature and humidity. This test is particularly adapted to the needs of the electronics industry.

Its salient features are robust construction, Good thermal insulation, User-friendly variable positioning for test specimens, External heating of test chamber. Test specimens may also be lifted into the test chamber by crane thanks to the lightweight test chamber hood which opens to 75°. It has an Ergonomic arrangement of the operating panel and display instruments, Operation, program and set value selection via color touch panel, Digital set and actual value displays.
