Campbell CR1000 Data Logger

The CR1000, Campbell Scientific's most popular logger, combines extensive measurement and control capabilities with low power consumption and rugged build quality. Designed to operate reliably in challenging environments whilst offering the flexibility to work with most sensors types and a wide choice of communication options. The CR1000 is supported by a range of peripherals, software and accessories.


The logger not only measures sensors but also drives communications, controls external devices such as relays or pumps and provides four megabytes of non volatile on board data storage. The logger is programmable using Campbell Scientific's proprietary software language CRBasic, which as the name implies, utilises BASIC like instructions to operate data processing and analysis routines.
