GLOBAL WATER GL500 Multichannel Data Logger

Features:
Multichannel datalogger for recording a variety of sensor signals
Includes both USB and serial communications 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
Batery powered for remote locations
User friendly Windows and Windows™ CE-based PDA software included
Global Water's rugged GL500-7-2 Global Logger offers state-of-the-art technology for continuous datalogging, storage, and retrieval. The logger features 7 analog channels and 2 digital channels for data recording. It also offers USB and serial communication ports for easy communication with a Windows™-based PC or PDA.  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.  The Global Logger includes 7 channels that can accept any 4 to 20 mA sensor, including many of Global Water's level, water quality, and weather sensors. The datalogger also includes two scalable digital inputs that accept switch closure signals from rain gauges or relays, as well as pulses from various external monitoring and control devices. The logger provides switched power to analog sensors based on sample interval and sensor warm-up time settings. You can quickly connect sensors to the datalogger's terminal strips, and you can easily calibrate sensors using the Global Logger II software.
