Water Quality

Products for Stand-alone Water Quality Monitoring and Control

Campbell Scientific builds systems for unattended, long-term monitor-

ing of water quality in many natural and industrial environments, in-

cluding streams, watersheds, wells, caves, water/wastewater treatment

plants, aquaculture operations, landfills, and processing plants. Our

systems include Campbell dataloggers, and a huge variety of sensors

and communication peripherals, customized for each application.

Dataloggers used in Water Quality Monitoring

Our dataloggers feature wide operating temperature ranges, low

power consumption, and the ability to directly interface with a

large variety of sensors. Because our dataloggers operate on bat-

teries (with or without solar panels), they are ideal for long-term,

stand-alone operation, such as at remote streams or wells. Most of

our dataloggers are expandable using multiplexers and other pe-

ripherals. Data are typically displayed and stored in the desired units

of measure (e.g., specific conductance as mS/m, µS/cm, Ohms).

Powerful on-board instruction sets allow unattended control decisions

based on time or conditional events. For example, if measured water

quality levels are outside a predetermined range, the datalogger can

actuate water samplers, sound alarms, open valves, actuate injectors,

and make a phone call to report conditions. The dataloggers can easily

provide the necessary water sampler control to meet EPA-mandated

first-flush and follow-up sample schedules. All data is time-stamped

and data from event-triggered samples is marked for later analysis.
