There was a time when manufacturing custom scientific equipment for a project was only available to the elite; a time when environmental data was only available to governments and subject to the political pressures of the day. Atlas Scientific is working hard to end those days. We are the new scientists, all of us. Reading the Electrical Conductivity (E.C.), total dissolved solids and salinity of water, was notoriously hard to do. With little information available on the subject, many engineers had to abandon their goal of adding a conductivity circuit to their design. Atlas Scientific has finally put an end to this problem.

The Atlas Scientific Conductivity Circuit is small, modularized, and designed specifically to read the conductivity, total dissolved solids and salinity of water.

The Atlas Scientific Conductivity Circuit is designed for both continuous and intermittent readings. After calibration, the Conductivity Sensor can be immersed in a liquid and operate continuously for 12 months before recalibration is recommended.

• Conductivity readings +/- 5μs

• Full Conductivity capability from 11μs to 92,000μs

• Temperature dependent or temperature independent readings

• Total dissolved solids (TDS) referenced to KCL

• Salinity is derived from the Practical Salinity Scale (PSS-78)

• Data output is a comma separated string: μs, TDS, Salinity

• Single reading or continuous reading modes

• Simple asynchronous serial connectivity (voltage swing 0-5v)

• Simple instruction set consisting of only 6 (not including calibration) commands

• Micro footprint circuitry

• Debugging LED's

• 5V operational voltage

• Dimensions: 18.4mm X 20.56mm (0.72" X0.80")
