Koster farm backed the need for an accurate and simple method of testing moisture in crops and was the basis for starting the manufacturing of the Koster Moisture Tester in 1948.
In 1986 at the age of 95 years, Ed Koster sold his company to the Faschian Family of Medina, Ohio. They are carrying on Ed’s tradition of a reliable product for a fair market price for over 40 years. We have since heavily expanded our offerings into all sorts of high-quality equipment and chemicals.
