Oakton® WD-56700-10 Eutech Instruments® pH 190 pH/ORP Digital Controller with Dual Setpoint & On/Off Control, Electrical: 80 to 250V

The pH 190 1/8-DIN controller displays the measured parameter value or temperature with a touch of a button. The user interface of the popular pH 200 series was simplified for quick set point review and programming. Entrance into the calibration mode is accomplished by simply pressing keys on the front panel--no need to remember and enter security codes. All information is displayed on the 14 segment LED display that is easy to read in low light installations. The controller has two relays that can be set for any combination of low/high level on/off (limit) control. Independently adjustable hysteresis provide accurate control in varying applications and prevents relay chatter near the set-point. All data is retained in non-volatile memory. The controller can operate in asymmetrical or symmetrical mode operation. Asymmetrical mode uses standard industrial pH electrodes and is acceptable for environments that are not electrically noisy. Symmetrical mode eliminates electronic noise problems when using electrodes with solution grounds. Order 100 Pt RTD pH or ORP electrodes with BNC pH connections separately. On/off (limit) control type. Two (high/low) set points. +/-0.01 pH accuracy. 0.01 pH resolution. 0.00 to 14.00 pH range. 1 mV resolution. +/-2 mV accuracy. 4 to 20 mA - 200 ohm max load output current. 2 SPDT (120 VAC - 6 A max; 240 VAC - 3 A max) output control. -999 to 1000 mV range. 4-digit - 14-segment LCD display. 0.1 degree C temperature resolution. 85 to 250 VAC - 50/60 Hz power. 100 Pt RTD temperature sensor. Dimensions: 3-3/4' width by 1-7/8' height by 6' depth. Manual or automatic from 0 to 100 degree C - 100O Pt RTD - 2 or 3 wire Temp compensation. Oakton #: WD-56700-10
