Model 3084 Bench Top, Line Powered, Microprocessor Based Five-Function EC Meter
The Model 3084 is a bench top, line powered, microprocessor based five-function EC meter designed to precisely determine the conductivity of aqueous solutions. The Function key selects Conductivity, Resistivity, High Purity Water, Total Dissolved Solids, Salinity or Self-Test. The instrument covers six ranges of conductivity (auto or manual) with a maximum full scale of 3300 counts. Measurement data is displayed on 2 lines by 20 characters per line, back lit dot matrix liquid crystal display. The Model 3084 features an RS-232 output for data logging to a serial printer or PC display.
