CR850

Measurement and Control Datalogger with Keyboard

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 UHF/VHF RF modems, and satellite transceivers. The CR850 datalogger uses external power supplies.
