This article explores automated data acquisition in chemistry using a handheld calculator, highlighting its benefits for students.
The LabWorks learning system is a computer- controlled data acquisition interface that allows students to quickly obtain and analyze chemistry data. This article describes how the LabWorks interface can be controlled with an HP 48G hand-held calculator rather than a personal computer. The calculator provides users with the same automated data acquisition as if a computer were controlling the interface, but it costs less and requires less maintenance and laboratory bench space. The types of measurements made by the system are discussed and a sample experiment described. Student data and comments are also presented.
