Who We Are.

Since 1977, Cortest has been the industry leading provider of high quality corrosion and materials testing equipment and has earned the reputation as the reliable go-to supplier of custom test systems. Throughout its history, Cortest has been involved in the testing industry, having previously provided corrosion testing services in its laboratories based in Houston, Texas, Columbus, Ohio, and Sheffield, England. The experience gained in our commercial laboratories significantly improved product design to assure safe and efficient operation meeting the specific needs of the researcher. Starting with the proof ring test system, Cortest’s product line has grown to include autoclaves, load frames, fume hoods, flow loops, deadweight testers, magnetic stirrers, DCPD systems, controls, software, and a wide range of specialty equipment. Many industry standard testing methods can be fulfilled using equipment specifically designed by Cortest to meet the requirements of the test standard.  Cortest systems are widely used worldwide in the oil & gas, nuclear, petrochemical, hydrogen and CCUS markets.

Using our standard products as a baseline, customers can work directly with Cortest engineers to cost effectively design a fully customized apparatus to meet their precise specifications. In addition to individual systems, Cortest frequently supplies fully outfitted laboratories including test equipment, fume hoods, safety systems, data acquisition systems, glassware, and other supplies. Cortest equipment is available with PED, CSA, CE, DOSH, and the China Special Equipment Manufacture License certificates (upon request).  Successful operation of Cortest equipment is assured via installation, training, commissioning, and refurbishment services, available worldwide. Continued growth has resulted in Cortest having been awarded Fast Track 50 awards on nine occasions (awarded to the fastest growing firms in our region) and in 2014, Cortest again doubled its manufacturing facility.
