Versatile controller/ transmitter offers three Dissolved Oxygen control mode: limit control, proportional pulse length control and proportional pulse frequency control. : : Accepts low range probes ( 0 to 10 ppm) and general range probes ( 0.5 to 40 ppm) : : Allows one point or two point DO calibration. Meter displays electrode information after each successful calibration. Previous calibration data is retained in the event unsuccessful calibration : : Automatic salinity and pressure compensation after manual input for more accuracte readings : : Option of Auto or Manual Temperature Compensation. Three-wire system compensates for cable-length resistance errors : : Galvanically-isolated, scaleable 0/ 4 to 20 mA output for high-quality output on peripheral devices
