Salt spray test chamber is the most reliable equipment for checking corrosion resistance of surface coatings when exposed to a salt-laden environment. This time-tested product has been specifically designed to assess the rust-proof ability of components to withstand corrosion due to atmospheric conditions. It provides complete flexibility in simulation of real life weathering conditions.

The temperature range for salt spray is 5°C above ambient temperature up to +55°C.

Salt spray test chamber is suitable for standard salt/fog testing in accordance with DIN EN ISO 9227 (DIN 50021),ASTM B117 and similar international test standards, and can be used with pH neutral salt solutions (NSS) or those acidified by the addition of Acetic Acid (ASS) or Cupric Acid (CASS).

Salt Spray chambers are commonly used to evaluate the corrosive properties of:
Phosphated surfaces (with subsequent paint/primer/lacquer/rust preventive).
Zinc and Zinc-alloy plating (see also electroplating).
Electroplated chromium, nickel, copper and tin.
Coatings not applied electrolytically (such as zinc flake coatings).
Organic Coatings.
Paint Coating.

Standard Features
Salt spray test chamber offers state of the art corrosion testing technology, reliability, ease of operation and easy maintenance – all at a remarkably affordable price.
Japanese Unique 7" color touch-screen operator control interface
Meet the requirements of continuous salt spray tests conducted at a single temperature only, such as ASTM B117 and similar international test standards with Neutral Salt Spray Test (NSS) or Acetic Acid Salt Spray (ASS) or Copper Accelerated Acetic Acid Salt Spray Test (CASS).
2 kinds of test specimen shelf: V-shaped and Round bar fits for different product type
Interior viewing window for clear observation for the test specimen
Consumables spares kit.
Hard-wearing acrylic salt spray atomizer(s)
Remove the salt spray to the sewer or outside from exhaust pipe at the back of chamber by pushing the button on the controller panel after test before the chamber is opened.
Highly accurate sensor made from platinum components for increased sensitivity
The glass atomizing nozzle insures the salt solution is introduced into the test environment evenly and at the proper concentration.
Low loading threshold for loading and unloading.

Optional Accessories
Chamber internal salt water tank could make automated testing for up to 72 hours, adding external storage tank(1000L), a tower level control and a salt spray solution reservoir level control to automatically refill the system could extend the testing time up to 7 days.
Push button controller for saving cost
Automatic pure water refill system
Air compressor
