The portable Series DW-U SB-LCD USB Data Loggers displays and r ecords 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.
