The CR850 is a smaller, research-grade data logger that includes an on-board keyboard display as part of its integrated package. It is intended for smaller configurations in which fewer sensors will be measured. Each CR850 reads input from sensors, then transmits the data via a communication peripheral; most sensors and telecommunication devices are compatible. Multiple CR850s can be configured as a network or units can be deployed individually. This rugged data logger can provide stand-alone operation in harsh, remote environments.

The CR850 consists of measurement electronics encased in a plastic shell with an integrated wiring panel, 16- character keyboard, and display screen. The display can show 8 lines x 21 characters (64 x 128 pixels). Custom menus are supported allowing customers to set up choices within the data logger program that can be initiated by a simple “toggle” or “pick list”. Its keyboard and display screen is used to program the data logger, manually initiate data transfer, and display data.

The CR850 uses an external  power supply. Low power consumption allows the it to operate for extended periods on a battery recharged with a solar panel—eliminating the need for AC power. The CR850 suspends execution when primary power drops below 9.6 V, reducing the possibility of inaccurate measurements.

The on-board operating system includes measurement, processing, and output instructions for programming the data logger. The programming language, CRBasic, uses a BASIC-like syntax. Measurement instructions specific to bridge configurations, voltage outputs, thermocouples, and pulse/frequency signals are included. Processing instructions support algebraic, statistical, and transcendental functions for on-site processing. Output instructions process data over time and control external devices.
