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.

A 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.

Features

• 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
• 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)
• 24 kbyte ROM, 40 kbyte RAM
• Data format is mixed array
• Software support offered in LoggerNet (full-featured) or Short Cut (programming)

Specifications

• Scan rate: 80 Hz
• Serial I/O port: 1
• Analog voltage resolution: to 50 nV
• A/D bits: 16
• The number of analog inputs, pulse counters, switched voltage excitations, digital I/O ports, and continuous analog outputs vary depending upon your card configuration
