Online Dissolved Oxygen Analyzer the Right Features To Measure, Analyze And Control pH, Dissolved Oxygen And Temperature
  • 5 programmable on/off relays: 2 for pH, 2 for D.O. and 1 for temperature.
  • Automatic temperature compensated (ATC) pH and D.O. readings.
  • User selectable salinity and pressure compensated D.O. readings.
  • Programmable hysteresis for customized control.
  • RS-485 output for remote access via an IBM compatible computer. This allows multiple units to be connected, ganged, together.
  • Simultaneous display of: pH, D.O., temperature, relay status and transmitter current mA output.
  • Clear, bright LCD with manual backlight switch for added visibility in dark working conditions.
  • Setup and calibration are done through a friendly, user-guided menu.
  • Convenient pH calibration with automatic buffer recognition of US and European buffer sets. Calibration data is stored in memory and is ready for use on power up.
  • D.O. readings only requires one point calibration.
  • Included panel mount bracket tightly secures the analyzer.
  • Standard ¼ DIN size.
  • Performs self-diagnostic at power up to ensure proper operation.
  • Analyzer is in a complete watertight case (IP65).
