Datalogging Conductivity/TDS Meter Records data in the plant or field for later computer storage and analysis Automatically records up to 16,000 data points in the field along with time and date. These can later be downloaded to a computer via the meter's USB port and the results viewed instantly on software which comes with the unit. The software also enables real-time datalogging directly from the meter to the computer. Simultaneously displays conductivity or TDS and temperature. A user adjustable ATC coefficient enables absolute (non-temperature compensated) measurements, as well as accurate measurements in solutions other than water.
