CR850 Datalogger

The cr850 datalogger is similar to the cr800 datalogger, except it has a keyboard display as part of its integrated package. The cr850 provides a lower-cost datalogger alternative for measurements of a limited number of sensors, yet can be used with most of our telecommunication devices such as cellular telephones, rf uhfvhf rf modems, and satellite transceivers. The cr850 datalogger uses external power supplies.
