CR3000 Micrologger®

The CR3000 Micrologger® is a self-contained, rugged datalogger that can measure most sensor types directly, communicate via modems, control external devices, and store both data and programs in either non-volatile Flash memory or battery-backed SRAM.

The CR3000 has an integral, 8-line, alphanumeric display and power supply. A battery-backed, real-time clock and 4M of nonvolatile data storage is included. The CR3000 is available with a sealed rechargeable battery base, an alkaline base, or in a low-profile version without batteries.
