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
