Our History

Our founder, Christopher Koehn, was hired by Stotz Feinmesstechnik GmbH from Gerlingen Germany as President of the newly formed Stotz USA LLC company and it was officially opened Freeport IL.  Economic troubles worldwide in 2010 caused the closure of all offices of Stotz with the exception of the headquarters in Gerlingen, Germany.  To support the existing customer and continue to build the brand, Stotz signed an agreement with Advanced Machine and Engineering from Rockford IL.  Christopher Koehn was hired by them to continue to manage and grow the product.  In 2015, Chris left the company and formed Air Gaging LLC.  In 2018, Air Gaging LLC officially bought out the inventory and customer list for the air gaging segment only from Advanced Machine and Engineering.  In 2019, Air Gaging LLC added the Metro product lines from Metro S.A. based in France.
