Company Founder

Mike Macauley, President

Mike has owned and operated the company since its inception. He is an expert in corrosion chambers and can train users on all types of corrosion equipment and a wide range of methods.

Mike can also perform calibration services on all environmental cabinets with a wide range of controllers. This includes temperature & humidity, thermal shock, altitude, agreeing, and many refrigerated systems.

Mike positioned his company in Michigan (USA) because this state has the largest population of chamber manufacturers and is the central location for this type of research and testing equipment used in the transportation industry. These manufacturers include Thermotron, Weiss, Russells, Espec, and Cincinnati Sub-Zero.

Mike's goal has remained the same over the last thirty years: to provide 100% quality services in a timely manner to all our customers.
