ECD DO90 Dissolved Oxygen Sensor

DO90 Dissolved Oxygen Sensor

DO90 Dissolved Oxygen Sensor

Engineers responsible for maintaining boiler operations will find the Model DO90 Trace DO2 Sensor from Electro-Chemical Devices (ECD) is designed for the continuous and highly accurate measurement of trace levels of dissolved oxygen, helping to maintain oxygen-free boiler feed water and reducing corrosion.

ECD’s Model DO90 Trace Dissolved Oxygen Sensor offers reliable and effective monitoring of boiler feed water. Oxygen should only be present in trace quantities in boiler feed water, as excessive concentrations of oxygen can result in corrosion damage to the components of the steam cycle. Boiler feed water is thermally and chemically degassed to achieve oxygen-free water, a state which must be maintained throughout the steam cycle.

The Model DO90 Trace DO2 Sensor is a lead-silver galvanic sensor with a durable PFA Teflon membrane. As a digital sensor, all of the signal conditioning, calibration and diagnostic functions are performed inside the sensor. Its signal is noise-free and it features zero calibration and air calibration.  

The Model DO90 flow cell has been specially designed for use with the Model DO90 Sensor. The orientations of the inlet and outlet sample lines automatically purge air from the flow cell. The measurement chamber is optimized for fast response and all wetted parts are 316L stainless steel. The DO90 sensor is also compatible with ECD’s T80 Analyzer, which also works with all Model S80 Sensors.

The DO90 Sensor offers a large measurement range, from 0.001 to 20.00 mg/L.

Long-term stability means that drift is less than 1 percent per month.  Needing virtually no maintenance, the DO90 sensor has an easily replaceable electrode cartridge, eliminating the need for messy electrolyte/membrane replacement kits.

The Model DO90 Trace DO2 Sensor is available as separate components, sensor, fittings, flow cell, Model T80 Transmitter or as a complete panel mounted system. The panel mount system is a complete plumb-and-play device. The system is also available as a complete kit, less the panel, for mounting to an existing water panel. Installation of the flow cell is also easy, using either the clamp style holders for wall mount or the two 10 x 32 threaded ports on the backside of the flow cell for panel mounting.

    Seawater Dechlorination Analyzer

    Seawater Dechlorination Analyzer

    Seawater Dechlorination Analyzer

    The Model DCA-23 Seawater Dechlorination Analyzer from Electro-Chemical Devices (ECD) is a low maintenance measurement solution that requires no chemicals to monitor seawater chlorine levels accurately in a wide range of industrial process and municipal water treatment applications.

    Seawater has multiple process industry uses, including heat exchange systems at LNG terminals, oil/gas refineries, electric power plants and SWAC systems (salt water air conditioning) in commercial buildings. The DCA-23 is a single-purpose analyzer that monitors chlorine in seawater from 0.0 to 2.00 ppm. It features an economical, low-maintenance design that requires no chemicals.

    The analyzer measures the pH, temperature, and Total Residual Oxidant (TRO) of seawater and converts them into an equivalent ppm chlorine value, which is displayed to conform with existing conventions. It features a minimum detection limit (MDL) of 0.014 ppm and a limit of quantification (LOQ) of 0.044 ppm, making the DCA-23 Analyzer suitable for monitoring in environments with the most stringent dechlorination regulations.

    The DCA-23 features three sensors, pH, TRO and temperature. The pH sensor measures from 0-14 pH, the TRO sensor measures from ±1500 mV and the temperature sensor measures from 0-100°C.  The DCA-23 with its tri-parameter monitoring, is the ideal seawater chlorine analyzer for a wide range of applications.

      ECD T80 Universal Transmitter

      T80 Universal Transmitter

      T80 Universal Transmitter

      Process and plant engineers in search of a powerful process analyzer for multiple analytical measurements will find that the Model T80 Universal Transmitter from Electro-Chemical Devices, Inc. provides a versatile, easy-to-use, economical solution for virtually all liquid analytical measurements.

      Featuring a highly intelligent digital transmitter protocol, the T80 Universal Transmitter simplifies process measurement and reduces maintenance costs for seven common industrial plant parameters.   Process measurement has never been easier or more affordable than with the T80’s virtually plug-and-play capabilities, which simplify daily operations and maintenance while reducing instrumentation costs simultaneously.

      The ECD Model T80 Universal Transmitter is a single channel transmitter designed for the continuous measurement of multiple parameters in a general-purpose industrial environment: pH, ORP, pION, Dissolved Oxygen, Turbidity, Conductivity or Resistivity. The Model T80 digitally communicates with any ECD Model S80 Intelligent Sensor and automatically conīŦgures the transmitter’s menus and display screens to the measured parameter. The Model T80 automatically configures to any of the listed measurements so that there is no need to inventory multiple instrument types, saving time and reducing plant operating costs.

      The T80 Universal Transmitter is flexible and user-friendly. It offers membrane switch navigation, a simple menu structure and soft key menu choices and an easy-to-read 2 ¾ -x- 1 ½ inch LCD display. The T80 accepts any S80 intelligent sensor or any standard pH, ORP or pION sensor with solution ground using the optional T80 input card. It is available with 4-20 mA output with MODBUS RTU on 24 VDC and 110/220 VAC instruments. The T80 can be configured with optional HART 7 communication and an optional three alarm relay.
