Eutech pH/ORP Controller/Transmitter, 190 pH, 1/8-DIN-Sized Housing

The Oakton Eutech WD-56700-10, pH 190 Controller/Transmitter has a 1/8 DIN-sized housing, LED display and two set points, and single pole double throw (SPDT) output relay with on/off control. A pH/oxygen reduction potential (ORP) controller/transmitter is used to measure pH, mV and temperature of a substance in various types of water control, such as fish ponds, and acid and/or base feed in aquaculture. This controller features a scrolling, 14-segment LED display to guide set-up functions and display indicators. It has manual or ATC, and push-button operation with calibration at two set points for ease of use. The controller has a universal power supply from 85 to 250V AC/DC to withstand electrical fluctuations, and it has removable terminal strips to ease field setup. Its 1/8 DIN-sized housing includes mounting hardware for ease of use and installation. It has output control of two SPDT relays at 120 VAC, 6 A max, 240 VAC, 3 A maximum. It has two galvanically isolated current outputs of 4 to 20mA, 200 Ω max load for remote monitoring or hard copy recording. It has two-level password protection for security, and removable terminal strips for ease of connections. The controller has two independently programmable hysteresis bands to prevent rapid contact switch at either set point. It has a water-resistant, Ingress Protection (IP) 66-rated housing, for protection against solid objects or liquids.

The WD-56700-10 pH/ORP controller has an ambient temperature operating range of 0 to 50 degrees C (14 to 122 degrees F) with 10 to 95% non-condensing relative humidity. Its pH range is 0.00 to 14.00, resolution 0.01, accuracy + or - 0.01. Calibration at 2 points with 7 buffer values (1.68, 4.01, 6.86, 7.00, 9.00, 10.00, 12.45). mV range -999 to 1000 mV, resolution 1 mV, accuracy + or - 2.0 mV. Temperature range is -10.0 to 110.0 degrees C, resolution 0.1 degree C, accuracy + or - 0.5 degrees C, calibration offset to + or - 10 degrees C. Hysteresis is adjustable; 0.0 pH to 2.0 pH, or 0 to 300 mV in ORP mode. It has a nonvolatile memory to maintain set-up if power fails, and has protections against electromagnetic interference. The controller’s dimensions are 6(d) x 3.75(w) x 1.875(h) inches (150[d] x 96[w] x 48[h]mm), it weighs 300g, and it is used with 85 to 260V AC/DC, 50-60 Hz. Use with BNC-connected electrodes (sold separately).

A controller/transmitter reads parameters, and automatically adjusts the solution to the programmed set points. It is used to monitor and control parameters in process water, wastewater treatment, chemical processes, and aquaculture applications.
