Orion Star 212

Benchtop Conductivity Meter

The Orion Star 212 Benchtop Conductivity Meter will acurately and reliably record  conductivity, total dissolved solids, salinity, resistivity and temperature measurements.  It is ideal for a wide range of applications and advanced conductivity analysis in the lab. Set temperature compensated readings using linear, non-linear pure water or EP options with 5, 10, 15, 20 or 25 °C reference temperatures. Perform up to a five point calibration, log up to 2000 data point sets with time / date stamp and easily transfer calibration and data logs via USB or RS232 to a printer or computer.
