Make any pH meter a dissolved oxygen meter with the Thermo Scientific™ Orion™ Dissolved Oxygen/BOD Probe.

  • Polarographic O2 sensor plus solid-state circuitry in probe top; converts current to voltage for direct DO readout
  • Plug probe into benchtop or portable pH meter, read DO over 0 to 14ppm range
  • Accuracy, ±0.05ppm/2% of reading, whichever is greater, at 15° to 35°C (59° to 95°F) (sample temperature within 10°C of calibration temperature)
  • Dual thermocompensator corrects for membrane permeability and O2 solubility
  • Ideal for BOD testing: overflow funnel supplied fits 300mL BOD bottle; built-in magnetic stir bar
  • Responds to 96% of change in <30 sec.; O2 consumption 0.1μg/hr.
  • Screw-on membrane/electrolyte module; no membrane replacement — simply replace module after 3 months of use
