Dwyer DLI數顯壓力數據記錄儀The Series DLI LCD Data Logger gives instant remote readings of temperature, humidity, or atmospheric pressure. The large, back-lit LCD and 8-button keypad provide convenient access to current data and recorder setup as well as memory and battery levels. The wall-mountable data logger can store at least 87,000 readings per channel. The easy to use DL700 software makes creating permanent records, performing data calculations, and graphing of data simple. The DLI can easily be started and stopped from a PC or delayed to start up to six months in advance. It can also stop recording at a specified time or after a certain number of readings have been taken.
