Dissolved Oxygen Analyzers/Transmitters, 2wire / 4 wire

ODM-135A (2 Wire) Features

  • Microprocessor based 2-wire transmitter suitable for field installation. The unit features isolated inputs and outputs, digital display and rain proof construction.
  • Simple Span Calibration
    The instrument can be calibrated in one action by virtue of memory- resident saturated DO (dissolved oxygen) data. A built-in stabilization determination function enables the unit to be calibrated accurately without operator error.
  • Automatic determination of electrode quality
    During calibration, the electrode quality is automatically evaluated. If the electrode quality has deteriorated to an unacceptable level, an error message is generated.

ODM-136A (4 Wire) Features

  • Microprocessor based 4-wire transmitter suitable for field installation. The unit features isolated inputs and outputs, digital display and rainproof construction.
  • Simple span calibration: The instrument can be calibrated in one action by virtue of memory resistant saturated DO (Dissolved Oxygen) data stored in the memory.
  • The built-in stabilization determination function enables the unit to be accurately calibrated preventing operator error.
  • Automatic determination of electrode quality: During calibration, the electrode quality is automatically evaluated. An error message is generated when the electrode quality deteriorates to an unacceptable level.
  • Output range adjustment. The output range can be easily reconfigured.
  • Output signal can be frozen during maintenance work: By switching to ST-BY (Stand By) mode the output value can be held to avoid disruption to the process control system.
  • Facility to receive external contact switching signal to hold output (for example, during electrode cleaning etc).
