Multichannel Datalogger for Recording a Variety of Sensor Signals

Powerful Recording
The GL500-7-2 can record over 40,000 readings and has four unique recording options: fast (10 samples per second), programmable interval (1 second to multiple years), logarithmic, and exception. The datalogger also has a sample on demand input that triggers a recording of special events. Daily start and stop alarm times can be programmed to limit recording intervals.

Features
• Includes both USB and serial communication ports
• Four sample modes: 10 times per second, timed, logarithmic, and exception
• Monitor up to 9 sensors at a time in addition to battery voltage
• Battery powered for remote locations
• User friendly Windows™ and Windows™ CE-based PDA software included
• Accepts any 4-20 mA input

Smart Software
The GL500-7-2 includes Windows™- based Global Logger II software, which makes accessing stored data and setting options easy. The software provides many useful features, such as real time readout, measurement interval and engineering unit selection, station ID setting, and sensor calibration. The Global Logger also includes Windows™ CE-based PDA software for simple data collection in the field. Downloaded data can easily be opened in any PC spreadsheet program for analysis and graphic presentation.
