The SMART Link 3 software allows test data to be transferred from a LaMotte instrument to a personal computer. The software relates a set of test results to a particular testing site and date. It gives the user the ability to input site names and unique ID numbers into a table for reference when managing a test record database. This allows the user to keep accurate, historical records of tests performed at specific sites, and export data to Excel and other programs to prepare spreadsheets and to graph test data.
