The Global Water data logger model GL500-7-2 multi-channel datalogger features 7 analog channels and 2 digital channels for data recording. The GL500 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, such as when a water sampler was triggered, when a door was opened, etc. Daily start and stop alarm times can be programmed to limit recording intervals during a day. The Global data logger is setup to accept any 4-20 mA sensor. The GL500 provides switched power to the sensors based on the sample interval and sensor warm up time settings. 2-wire and 3-wire sensors can be quickly connected to the datalogger's terminal strip and calibrated via the Global datalogger software. The datalogger software has online help files that are easily accessed using drop down menus and links to quickly find the answers to your questions. The data recorder has an optional rugged, lockable and weather-resistant enclosure that can easily be hidden, bolted to a post, or secured inside an additional container for added protection from the elements, animals or vandals. A 12VDC rechargeable battery and battery charger comes with this option.
