This controller/transmitter offers sophisticated operating features in a rugged NEMA 4X (IP65) rated housing. Mount the controller virtually anywhere<emdash> it is wall, panel, or pipe mountable. Backlit LCD with programmable contrast and illumination duration displays conductivity and temperature.

Controller accepts 2 or 4-cell conductivity electrodes with cell constants between K= 0.01 and 10.0 and is capable of measuring seven different ranges up to 1000mS/cm. Select the pure water temperature compensation curve to correct for non-linear water temperature compensation for the 0 to 2.000 <micro>S/cm range. New, 4-electrode conductivity cell eliminates polarizing effects ensuring more accurate measurements in highly conductive samples. Order 100 or 1000 <omega> Pt RTD cells from accessories or the conductivity cell section.

Programming and calibration sections are protected by two level password protection. All programmed parameters are stored in non-volatile memory which retain settings even when power is lost allowing user to configure controller prior to installation.

Dual 0/4-20 mA scaleable outputs for conductivity and temperature provide information for control systems, pumps, or recorders. Select from automatic or manual temperature compensation using 2- or 3-wire 100 or 1000 <omega> Pt RTD conductivity cells. Two relay outputs are programmable for high and low set points, hysteresis, and delay for precise control.
