Easy to use, easy to maintain
Because the instrument is simple to use and maintain, operator training is minimal. On-board self diagnostics monitors the instrument function to help guarantee accurate results and alert operators to errors. YSI analyzers are currently part of the manufacturing process for hundreds of food and beverage products. YSI maintains a library of application notes describing measurement techniques ranging from the measurement of dextrose and sucrose in potatoes, cereal products, and molasses, to the measurement of choline in infant formulations. A more recent application involves measuring lactate and ethanol in tomato processing to quantify microbial load.
