CR800 is a low-cost and compact research grade data collector with differential channels. It contains three differential channels that enable sensor connections for differential signals. This series of data collectors has two models: CR800 and CR850. Among them, the CR800 can be connected to an external CR1000KD handheld display, while the panel of the CR850 already integrates a display and operation keyboard, making it convenient for manual transmission, reading, data storage and other operations. The CR800 series can be accessed through the Internet, wireless radio CDMA/GPRS、 Remote transmission of data via satellite. In addition, it can also be directly connected to a PDA for operation. Users can also choose the SC115 2G data storage USB flash drive, which is equipped with both CS I/O and USB interfaces. The observation data collected by the data collector can be stored through CS I/O, and the USB interface can be directly connected to the computer. It can be used as a storage medium to transfer data between the data collector and the computer, as well as to achieve direct connection between the data collector and the computer.
The CR850 has the same performance as the CR800, but integrates a LCD display and an operation keyboard, which can be used for on-site settings and status checks.
