Overview
The CR7 is a precision instrument that is primarily used in multi-parameter research and industrial applications. Each CR7 system is individually configured to meet the specific measurement needs of the customer.
This control module is the base of the measurement system, then the input/output module, datalogger enclosure, and I/O cards are added. As measurement needs change from study to study, the CR7 can be adapted by modifying the I/O card configuration.

Benefits and Features
- Collects and stores data and controls peripherals as the brain of your system
- Suited for applications that require high resolution (e.g., thermocouples) or a large number of input channels
- Up to seven I/O Cards (CR7 720) or fourteen I/O Cards (CR7 720XL) can be inserted to configure a system for specific applications
- Stores 280,000 data points
- Mixed array data format
- Software support offered in LoggerNet (full-featured) or Short Cut (programming)

Detailed Description
The CR700X control module is the main component in a CR7—a large modular datalogger. It is ordered with internal PROMs (firmware) and temperature testing. The CR700X contains the system's CPU, ROM, RAM, a serial interface for communication with data storage/retrieval peripherals and connection of up to four I/O Modules (typically one alongside the CR700X and three at some distance to the CR700X), and a keyboard/display. Refer to the Configuration tab for software compatibility.
The CR700X also accommodates:
- PROMs (detailed in the Ordering information)
- 3259 Battery (included; formerly known as the LA700)
- CR709 Memory Card (ordered separately)
A complete CR7 consists of:
- CR700X
- I/O Modules (either the CR720 or CR720XL)
- A mix of I/O Cards
Modular design consists of:
- Control module (CR7 700X)
- Input/output module (CR7 720 or CR7 720XL)
- Field or laboratory enclosure (ENC 7F, ENC 7XL, or ENC 7L)
