Compact Dataloggers, DW-USB
The compact design of the DW-USB Series data loggers allows the user to monitor temperature, humidity, dew point, voltage, or current almost anywhere. The user can select the sampling rate, start time, high/low alarm settings, and temperature unit parameters with easy to install Windows® base software. Stored data is downloaded by simply plugging the module into a PC's USB port with no cable required. Alarm status and low battery is indicated via buit-in flashing LED's. When the protective cap is fitted, the data logger resists moisture to IP67 standards. These features make the data logger ideal for calibration labs, pharmaceutical plants, environmental chambers, and storage warehouses.
