The USB-5104 four-channel, battery-powered, thermocouple data logger, featuring an LCD display, can measure and log temperature in an array of applications. Developed by Measurement Computing, the device measures J-, K-, T-, E-, R-, S-, B-, or N-type thermocouples and is able to store up to 1.9 million measurements. High and low alarms plus a burst logging mode enables the logger to vary sampling intervals based on changing temperature conditions. Start, stop, and restart pushbuttons facilitate the data-taking process. The logger sets up via included software and through a UBS connection. Logging duration depends on the selected logging interval and mode. Data can be saved to numerous formats, including .csv for Excel.
