Oakton® WD-53400-05 Eutech Instruments® DO 1000 Dissolved Oxygen Digital Controller with Dual Setpoint, On/Off & Proportional Controls, Electrical: 220V

Use this controller for precise dissolved oxygen (DO) control of your wastewater or aquaculture process. Select from on/off - proportional pulse length - or proportional pulse frequency control types. Two set point - two SPDT relay operation lets you set low/low - low/high - high/low - or high/high control. Separately adjustable hysteresis bands prevent rapid contact switching near the set points. Independent 100 percent and 0 percent saturation calibrations ensure high accuracy over the entire range. Key in the salinity of your solution and the barometric pressure-controller automatically corrects the readings to these offset values. Scalable 0-20/4-20 mA recorder/transmitter output lets you make hard copy records of your data. Nonvolatile memory maintains setup parameters even when power is shut off. Two-level password protects all settings. Specifications: proportional pulse length - pulse frequency - or on/off (user selectable) control type. 0.00 mg/l (ppm) to 20.00 mg/l (ppm) range. Percent O2 saturation range is 0.0 percent to 200 percent. Temperature range is 0 to 50 Degree C. 0.01mg/l (ppm) resolution. Percent O2 saturation resolution is 0.01 percent. Temperature range is 0.1 Degree C. +/-1.5 percent full scale mg/l (ppm) accuracy. Percent O2 saturation accuracy is +/-1.5 percent full scale. Temperature is +/-0.5 Degree C. Manual input from 0.0 to 50.0 ppt - automatic offset of measurements salinity compensation. Automatic - 0 to 50 Degree C or manual from -9.9 to 125 Degree C temperature compensation. Manual input from 555 to 808mm Hg; automatic offset of measurements pressure compensation. Control output relay is 2 SPDT relays - 6 A at 110 VAC - 250 VAC max. Control output current Isolated 0-20/4-20 mA - 600 ohm max load - programmable boundaries. Control output alarm 1 SPDT relay - 6 A at 110 VAC - 250 VAC max. Dual display of DO reading plus temperature. Pulse length (0.5 to 20 sec) or pulse frequency (60 to 120 pulses per min). Oakton #: WD-53400-05
