Kett was started by four engineers in 1946. After initially introducing a wood moisture tester and metal detector, it was their vision to design and manufacture portable handheld moisture analyzers. The goal was to provide a rice farmer with the same level of measurement quality available within government test labs. As is still true today, the customer depended on the accuracy of this measurement and the reliability of his instrument to standardize the quality of his harvested rice product. This standardization would provide him with an optimal harvest yield, maximizing his return on investment.
