Our Mission

GVS Ltd was started in 1994 by two shareholders who had a lifetime of experience in all phases of the grain business. They both had a background in developing grain samplers and were confident the Port-a-Probe was the solution. GVS Ltd has most of the Port-a-Probe parts custom built, assembled and shipped by Custom Metal Fabricators, Inc. located at Herington, Kansas. Some parts are made in Kansas City.

GVS Ltd is now owned by one of the two founders. Many improvements have been made to the Port-a-Probe over the years and it is now perfected, evidenced by consistent performance for more than 17 years
