Corrosion testers are type of material testing equipment that monitor and test the effect of corrosion on the sample. You can use a corrosion tester to evaluate the effect of variations in temperatures, pressure or operating environment of an industrial component.

There are various techniques of corrosion testing as there are many parameters that cause corrosion. Some of the common corrosion testing methods are acoustic emission testing, optical testing, eddy current testing, radiographic corrosion testing and electrochemical impedance spectroscopy. Other corrosion testing methods are stress corrosion testing, metal corrosion testing and corrosion resistance testing.

Various reputable organizations like ASTM (American Society for Testing and Materials), ISO (International Organization for Standardization) and ASME (American Society of Mechanical Engineers) have defined standards corrosion testing methods. However, you can also opt for customized corrosion testing method as per your requirements and expertise on the corrosion testing.

Some important parameters you must consider before buying corrosion test instruments are:

1. Material of the sample subjected to corrosion testing
2. Type of corrosion test
3. Parameter causing the corrosion of the sample
4. Type of corrosion testers: a dynamic or static corrosion tester

Action Steps
The best contacts and resources to help you get it done

Buy corrosion test equipment from reputable manufacturers

Once you know your corrosion testing requirements, check out corrosion testers available in market. If you know the material of the sample you would be testing, compare the corrosion testers that can test these materials at various operating conditions. For example, you can buy metal corrosion testing equipment to perform copper corrosion test.

I recommend: Atlas Material Testing Technology offers corrosion testing instruments for laboratory testing in various industries, such as aerospace, automotive, electronics and telecommunications. If you want to determine the corrosion rate of steel reinforcing bar in concrete, check out the corrosion testers offered by James Instruments, a manufacturer of non-destructive test equipment for concrete and other coarse-grained materials. Corr Instruments supplies compact corrosion testing equipment for monitoring and measuring corrosion rate of metals at high temperatures and pressures.

Buy corrosion probes from reputable suppliers

Since corrosion probes are the end tool for some of the common corrosion testers, you need to buy good quality corrosion probes from reputable companies.

I recommend: Metal Samples Corrosion Monitoring Systems, a supplier of corrosion monitoring probes, can also provide customized corrosion probes as per customers’ requirements. Rohrback Cosasco Systems, a leading supplier of corrosion monitoring equipment, also supplies corrosion probes to the oil and gas industry.

Evaluate corrosion testing services available

If your corrosion testing requirements are not permanent, try using corrosion testing services.

I recommend: Corrosion Testing Laboratories can conduct custom corrosion testing and corrosion testing as per various standards set by ASTM, ISO and ASME. Metallurgical Engineering Services, a material testing service provider, also offers corrosion testing services. Nevada Automotive Test Center provides corrosion testing services for automobiles including commercial and defense vehicles.
