Water Quality Sampler System Controller
The Water Quality Sampler System Controller’s LCD display shows the type of sensor that is being monitored, the data reading and the engineering units.  The display also indicates if either relay has been triggered since last reset, which relay was triggered, and whether the maximum or minimum limit was exceeded.  Two separate relays are provided, one triggering the Water Quality Sampler System Sampler and the other for controlling all types of external devices including alarms, mixers, pumps, control valves, floodgates and telemetry systems.  Each relay is independently programmable to trigger on maximum and/or minimum levels in one of three different modes.

Water Quality Sampler System Sampler
Global Water triggered Water Quality Sampler System Samplers are enclosed in rugged, rainproof, lockable carrying containers.  Inside each standard water quality sampler container is a 2-gallon polyethylene waste water sample bottle for collecting composite samples, a peristaltic sampling pump, two knob control panel (No programming required) and a rechargeable gel cell battery.  Other options include glass sample bottles, refrigerated containers, portable ice containers and more. 

Water Quality Sampler Data Recorder
Global Water’s Water Quality Sampler Data Recorder works with MS Windows software.  The Water Quality Sampler Data Recorder monitors and logs both water quality value and time of the sample for your records.  Data downloaded from the Water Quality Sampler Data Recorder can easily be opened in any PC spreadsheet program for analysis and graphic presentation.
