Alpha RES1000 1/4 DIN Resistivity Controller / Transmitter

 

 

Product Features

 

:: The alpha-resistivity controller and transmitter offer two measurement ranges. High level of accuracy, ±1% of full scale is obtained in ultra-pure or R.O.applications, when used with the appropriate cells and correct temperature coefficient
:: Higher accuracy in resistivity readings is obtained by adjusting the Temperature Coefficient for the sample solution. The controller allows values between 0.0% to 10.0% to be input
:: In addition, for “Pure” water applications, a pure water compensation option is available to correct for the non-linearity of pure water temperature correction curves. Automatic or Manual Temperature Compensation options available
:: After each successful calibration, cell characteristics are displayed. It is useful tool in tracking the efficiency of cell. In the event of an unsuccessful calibration, previous calibration data is retained
:: Galvanically-isolated,scaleable 0/4 to 20 mA output for high-quality output on peripheral devices
