The portable Series DW-USB-LCD USB Data Loggers displays and records
temperature, humidity and dew point. The easy-to-read LCD display shows the current
temperature or humidity along with the minimum and maximum reading since last
reset. For applications that require more accuracy, a high accuracy temperature and
humidity model is available. Thermocouple models can accept any J, K, or T type
thermocouple with a mini-plug connector. Series DW-USB-LCD data loggers use a
free downloadable a Windows
®
based software which allows selection of the sampling
rate, start time, high/low alarm settings, and temperature unit application. For quick
downloading of data, the data logger can be plugged directly into a PC’s USB port
with no cable required. Downloaded data can then be graphed, printed, or exported
to other spreadsheet applications.
