Programmable Acetic Acid Salt Intermittent Spray Test Chamber with Precision PH Control

Programmable Salt Spray Cycling Test Chamber For Corrosion
and Temperature Humidity Test

Brief Introduction:

Salt Spray Test Chambers offer the most realistic and dependable corrosion test, widely used to test corrosion resistance of automotive, paint, surface coating, chemical, aerospace, electronic, car industry, offshore and defense industries.

Acidified Salt Fog Test (cyclic) can be used to test the relative resistance to corrosion of aluminium alloys when exposed to a changing climate of acetic acid salt spray, followed by air drying, followed by high humidity, all at an elevated temperature.

This test is also referred to as a MASTMAASIS test. Test specimens are placed in an enclosed chamber, and exposed to a changing climate that comprises the following 3 part repeating cycle. 0.75 hours exposure to a continuous indirect spray of salt water solution, prepared in accordance with the requirements of the test standard and acidified (to pH 2.8 to 3.0) by the addition of acetic acid.

This spray is set to fall-out on to the specimens at a rate of 1.0 to 2.0ml/80 cm²/hour. This is followed by 2.0 hours exposure to an air drying (purge) climate. This is followed by 3.25 hours exposure to a high humidity climate which gradually rises to between 65%RH and 95%RH. The entire test cycle is at a constant chamber temperature of +49C. The number of cycle repeats and therefore the test duration is variable.

Features:

1, Chamber material is made of P.V.C Sheet, sturdily and will not be out of shape.

2, Test chamber is heated from five directions to ensure the temperature is uniformity distributed.

3, Spray nozzle is specially made, enable to spray the salt water with considerable speed, then falls on the surface of samples.

4, Hot and moist air keeps the humidity in the test chamber conforms testing request.

5, High precision P.I.D. temperature controller limits the temperature difference within the range of ±0.1℃.

Specifications:

Please Note Small Type of 60 and 90 do not meet standard of ASTM B117.

Note:

1. The above specifications are for reference only, the actual specifications for the main quotation.

2. Custom made is available according to customers’ special requirements.
