Cotton lint has traditionally been marketed based on weight without regard to the lint moisture content (mc), but with restrictions regarding excessively high mc. Recently the industry recommended keeping the mc of lint in bales below 7.5% (wet basis) and the loan program added a definition of wet cotton as that which exceeded 7.5% at any point in the bale. So there is considerable interest in measuring the mc of lint in cotton bales, but there is no independent information regarding the operation of the commercially available meters. This paper will describe data collected with several available portable moisture meters with regard to accuracy, repeatability, speed of operation, and price.
